07 Stalling issue: Do you have it?

Okay, so I have heard about the 07 randomly stalling while cruizing at 40 mph down the road or at a stop light. However, thank God I have yet to experience this and I hope I never do. So my question is, is this a problem with the 07's or is it just the air/gas mixture is to lean when the dealers are putting it together? Has your bike stalled? [Mod: can you make this poll public?]

mine stalls every now and then... might be that I suck getting out of first... lol, I don't worry about it much...

They all do, just like the lag, all us bike will do it. :) Well except for Shanes............. his is still in a million pieces.... :lol :lol

They all do, just like the lag, all us bike will do it. :) Well except for Shanes............. his is still in a million pieces.... :lol :lol No stall problems yet,:sing: if i look for the lag its there but as of yet i have never been there with normal driving....but only done 100 miles:)

Mine does not do it anymore. Either from the mods I did or miles put on.

Never had a stalling problem...

My 07 has never stalled or died at any speed or at idle. However, my buddies 07 has died on him several times, but he only has 200 miles on it. I keep telling him to take it out and put some miles on it and let it breath a little. Also my bike does not have the lag @5500 in 2nd either! P.S. Just kidding about the lag. Couldn't help myself on that one.

Mine stalled 3 times one hot morning heading to work while splitting lanes. I mentioned it at the initial service. They reported that couldn't find anything wrong with the bike. Hasn't happened since that one time. I thought maybe it was heat related...and maybe it is, now that summer has finally hit LA, I'm sure I'll find out. Maybe it was bad gas, or the fuel/air mixture that others have mentioned. Of course, now that I've typed this, it'll stall all the way home. :)

I Have Never Had Mine Stall On Me While Driving... Everytime I Do A Cold Start Though It Stalls On Me About 2 Or 3 Times Before It Will Finally Stay Running!!! Am I The Only One Having This Problem?

I have about 500 miles, never stalled.

Never had a stalling problem... Same here, never had a stall problem.

1200 miles and not once.:thumbup

Mine has stalled a few times but never while just cruising. It has always been while stopping and it has only happened when compression braking and then shifting down RPMs drop to low and it dies.

never - runs like a champ

Mine only Stalls if i try to slow down , Slower than idle ( 8-10MPH) without the clutch Pulled in!!! then Clunk stall!!!! I Love my Bike!!!! Oh P.S. 1400+ Miles never stalled at 40 + MPH WTF ????

Mine did it for the first and second time ever last weekend. Luckily it was while I was sitting in a parking lot, not on the street. Came out after lunch and started the bike, blipped the throttle and it died... restarted and did the same thing. I recently installed race baffles so I thought that might be the reason behind it.

You installed race baffles on the 07? I didn't think that was possible.

No problems. :thumbup

You installed race baffles on the 07? I didn't think that was possible. very possible.... and they are EFFIN LOUD!

Mine has done it in the past and yesterday it did it again. I was on 2nd between 5500 and 6000 rpm. When I hit the gas it stalled. It sucks. I am taking it for the 600 miles check up on monday let see what they have to say. I think once we put a full exhaust and a power commander the problem will go away.

mine stalled for the first time yesterday. i was slowing and downshifting into 2nd about 20 mph and it stalled.. i was rolling with the clutch in and hit the button. it fired right back up. first and only time. I have about 3200 miles on my 07 and it was hot , im in houston. bike was prob about 170 to 180 degrees.

2200 miles on mine. It has never stalled. I have never experienced the lag. Life is good up here.

very possible.... and they are EFFIN LOUD! Thats what my buddy tells me he won't ride behind me anymore because he says he can't hear anything. I love the sound though.

I stalled mine a few times, but that was all me learning to keep the revs up letting the clutch out. This is totally different from my down low grunt FZ1.

[Mod: can you make this poll public?]Hi,a customer of mine had this exact problem,did you ever find the cause?

I have the same problem from time to time with my 07. It will crank and crank, but won't fire for several seconds. Then I try again a second later and it fires right up. No problems starting at all when already hot.

Try standing it upright!!! Like lift it off the kickstand a bit and hold it level to the ground. It might have something to do with how the gas is sitting??? I Have no clue , but when i do this it starts up the first time all the time. Even Shimmy side to side and get the gas bouncin around!! Just my $.02 it works for me and , now i dont get uposet about this matter. Because having a brand new bike not start for you the first time you try is Very , very Frustrating. Just give it a try!!!:thumbup

Only had my 07 for a couple of days, so I haven't had any problems. Do you guys use Premium gas in your 07, or can you use regular? I know the manual says to use Premium.

93 octane goes without saying. That should be a no-brainer for ANY motorcycle, let alone an R1.

Do you guys use Premium gas in your 07, or can you use regular? I know the manual says to use Premium. Ofcourse!! Even when i Feel like having a little extra Power!! Try one of these!!!! this is Pill form. i Found it works better than the Liquid brands you'd find at a Gas station. but seriously that shyt works and you notice it so much more on your bike rather than your car!!! But use 1/2 the dose. directions are for cars!!! And Always use 93 some sunoco's or BP's have 93 +!!! http://www.dynotab.com/octanebooster.htm Or try my other favorite, Cant find a pic. but its in a yellow Bottle! Reading " OCTANE BOOST...JET FUEL....BARELEY STREET LEGAL"right on the Bottle, that is some mean stuff to put in this engine. and a very good SLEEPER mod. Cuz this gives you the added power to the wheel without a doubt!!! $.02:thumbup

93 octane goes without saying. That should be a no-brainer for ANY motorcycle, let alone an R1. I use 94 octane here, I love Sunoco!

My bike has stalled off and on since it was new. It has 2900 miles on it now and still stalles periodoically. It stalls when I pull in the clutch lever to downshift. Usually from 3rd to 2nd, or 2nd to 1st. This is really frustrating. It is also a safety hazard. I have had it stall on me in traffic with cars behind me. When I restart it, it won't idle. I have to apply throttle to get it to start and to keep it running. I believe its too lean, because it does not start well in the mornings either. My dealer said he hasn't heard anything about this, and he checked the TPS, but it seems to be OK. I sure wish my bike would not do this.

I put the graves Cat-eliminator and slip-ons on with a power commander mapped by them .It stalls when i cruise up to a stop and close the throttle no hiccup or anything . it idles fine but yesterday it left me in the middle of an intersection thumbing for the starter as traffic swerved around me . My guess is not the power commander it is not supposed to do anything to the fueling down low . will have to get someone to check it with an exhaust-gas analyzer

Mine hasn't done it. only 300 or so miles on it. But i've pushed the bike a little and have not experienced it....So far...

Our regular unleaded in the UK is 95 octane and we also have super unleaded that starts at 97 octane and some are even 98 octance.

No one else, eh? I'm thinking about replacing my bike that was stolen. However, looking at these numbers, there is a 50/50 chance that my bike is going to stall while just cruising down the road. I don't like the odds....

Mine stalled one time after i got done riding for a while and i stopped and i revved it up and then it just like shut off and never did it again since

I never had the problem..... until now. Two things have changed at once so I'm not sure whta has caused the issue. Stalls when cold at start up, also if you blip the throttle when cold. Whats changed? 1. new ECU installed 2. Akrapovic CF slipons installed Have had PCIII installed prior to changes and no problem before. Stock map on PCIII Any idea if one or both of these changes has now caused this problem???

[Mod: can you make this poll public?] I've owned 13 Yamaha's in my life so far. I now have the 07 R1 and I am having stalling problems. Coming up to a light or to a stop sign, in 2nd or 1st gear my bike will just die. Then I need to come to a complete stop or put it in neutral, turn the bike into a on position, wait for the servo motor to do it's thing, then I can turn the bike back on again. Happened to me all day today. Going to call dealership tomorrow.

My bike stalled yesterday after riding fifteen miles aprox 85mph temp 85, coming off the freeway to a stop idling in first just died, first time in 1200 miles. Seemed to run a bit rough before it stalled, could it be the throttle bodys out of adjustment, i have the tool might be my next job.

Ok i bought An 07 R1,, put PCIII slip ons,, Akropvic SP not new hex cans,,, GYTR RACE filter and appropriate map... then my bike would die at idle and have no power and stall out and bog,, at about 25% throttle. But this was only after riding and it would happen after a stop light etc... i have been trying to fix it and my dealer and another high tech dealer with all sorts of machines to fix this bike are failing to fix it,. ecu and all TPS"s have been replaced... with no results. i just bought this bike and got to ride it for a month.. now im missing summer,,., ANY HELP?!?!? suggestions? similar problems.. Andy42421188@aim.com thanks

Andy42421188@aim.com thanks Dude I only have 800-900 Miles on my bike and it does the ame. We should start to email yamaha. EDIT: On phone with Yamaha....... they documented but told me to contact my dealer and they will contact Yamaha.

Well mine had just clocked a 1000 miles when it started to mis-fire. Dropped a valve in one of the cylinders and it took 6 weeks of the dealer going back and forth with Yamaha until they got permission to strip and rebuild the motor. Also had the new ECU installed. It's running fine now with no stalling issues.

valve dropped wtf!

Yeah I probably got a bike with a motor that was built on either a Friday afternoon or Monday morning. The bike runs great now though.

No one else, eh? I'm thinking about replacing my bike that was stolen. However, looking at these numbers, there is a 50/50 chance that my bike is going to stall while just cruising down the road. I don't like the odds.... My bike stalled once when it had less then 100 miles on it. After I put the PCIII on it, the bike has never stalled at all. Does anyone have the stalling issue with a PCIII and CUSTOM map?

Mine stalled bone stock 3 times 2 weeks ago. I had my tps setting bumped up a few notches and it is fine now.

They tell me there is a newer ECU made to stop this problem...... now after a month of waiting... and yamaha has done nothing my dealer has contacted them several times!!! i just got mine back and its doing ok for now.

They tell me there is a newer ECU made to stop this problem...... now after a month of waiting... and yamaha has done nothing my dealer has contacted them several times!!! i just got mine back and its doing ok for now. My stalling problems were happening before I replaced my ecu. I replaced my ecu and I'm still having the problems. Bumped TPS few notches...EXPLAIN please. I still need to get either a PC3 or Fastcard. Heard the fastcard adjusts the R1 better since it uses a flyby wire.

Mine stalled bone stock 3 times 2 weeks ago. I had my tps setting bumped up a few notches and it is fine now. This is interesting facts, they talked about it at the shop yesterday but didn't know for sure, do you know if they adjusted the throttle valve-TPS, cable pulley-TPS or both on your bike? And turn up TPS a few notches, is that from stock value or was it out of range from the beginning? A nother thing, and this is a little confusing to me: The manual gives a very specific value for TPS adjustment, for example: "Throttle valve-TPS signal1" should be adjusted to 16 (degrees?), at throttle closed, but in the sensor operation table a span of 9 - 22 would be alright, how does that work?

Well nice to see I'm not alone here... When I 1st got my bike it used to stall now and then while downshifting or stop'n... Dealer said they didn't see anything wrong... Have about 1500 miles on it right now and although it did stall on me the other day, it has'nt really done it in a while and when it does stall, it starts right up... =/ Guess I'll give Yamaha a call.

my o7 r1 always stalls when it is cold if i start it up and even touch the gas it stalls it will do it 4 or 5 times until you can actually take off, and for the comment about puttin exhaust on and power commander on to fix the problem i alresdy have all that stuff and the problem still exists.:hammer:

My bike has stalled a few times upon deceleration. I don't need to stop and, catch neutral and all of that othe stuff. I simply pull in the clutch and then drop the clutch again to bump start it. While it is un-nerving, it has not happened enough to really piss me off.

Mine stalled once when it was on the first tank of gas... I chalked that up to cheap gas from the dealer. Never again has it happened though. I would still like to know if any of you that have this stalling issue have a PCIII and a custom map done? It could very well be a lean condition at idle that is causing this?

I had a pipe & PCIII put on before I pulled it out of the dealer, dyno tuned and all... and still stalls now and then.

I don't have time right now to read back through the thread, but I thought I remembered people saying they had the stall with PCIII and pipes :dunno

Okey, things are getting better (i hope). The shop called and said it was the TPS that was broken. It didn't show in the diagnostics but when they measured it, the values where off, they haven't changed it yet but i really, really hope it will work now. :thumbup

And if that was broken would'nt it make the bike always stall... not just stall once in a blue.

Throttle Position Sensor and Yamaha has been famous for having problems with them. The 04 -06 went through a recall over them. From my experience with Yamaha Banshee Quads, it is one of the first things removed when the modding begins.

From my experience with Yamaha Banshee Quads, it is one of the first things removed when the modding begins. Well as I said before... would'nt that make the bike run like shit all the time? I mean if that is the problem then I would think the bikes would always be stalling, not just occasionally. I mean mine went almost 1K miles without doing it again... :dunno

As yamahog said, the -04 to -06 behaved the same way so yes, it wouldn't be to hard to do the maths in this case to. My -05 went ~50000km before the problem first occurred, and just ones. There are two TPSs, one for the throttle grip and one for the throttle valves, they both have dual resistors, i don't know if that is for fail safe or more accurate measurement, all i know is that the fault code reading showed nothing wrong but when they measured it it gave the wrong values, don't know more for now. And as i said, i don't know if it work yet but i hope i know tomorrow.

I had a pipe & PCIII put on before I pulled it out of the dealer, dyno tuned and all... and still stalls now and then. What is your a/f ratio at idle? any idea? Just as a test I would richen up your "LOW" on the PCIII by a couple of bars and test it out. It couldn't hurt to try this.

My bike has stalled a few times upon deceleration. I don't need to stop and, catch neutral and all of that othe stuff. I simply pull in the clutch and then drop the clutch again to bump start it. While it is un-nerving, it has not happened enough to really piss me off. It's not acceptable though is it, especially for a new bike.

I've got another -07 R1 and it runs much better than the previous one but some times it have a fragment of the same tendences as the first one when downshifting/motor breaking to a halt from a steady speed. Thinking about it, perhaps it's the O2 sensor that upsets the FI? Using a PCIII often involve removal of the O2 sensor just because the O2 sensors involvement in steady cruise conditions. Dyno Jet have an eliminator to simulate a steady O2 value(?), how will the stock FI react using the O2 eliminator without a PCIII and does the ECU have some adaption function with a memory for the O2 system? O2 eliminator: http://66.132.187.175/ps-1401-48-o2-sensor-eliminator-kit-yamaha.aspx

I never had the stalling issue with the old computer, as soon as I got the new computer installed I started having stalling issues, when rolling to a stop. I removed the o2 sensor and had the pciii and full system all installed before I changed the computers and it didnt stall before. So Im left with the assumption that it is in the computer, now how to fix it?

So Im left with the assumption that it is in the computer, now how to fix it?So you had the PCIII connected both before and after you swapped the ECU but the stalling came with the new ECU? Did you make any other changes at the time, may i ask why you had to change ECU and was it brand new? Do you use some kind of O2 eliminator or did you just disconnect it? I was going to advance the TPS some degrees to see if it make any difference but reading about your experience i'm not to sure it will do any good.

So my bike stalled for the first time today coming off the freeway, i was doing about 80kph(50mph) taking an exit onto another freeway and my bike went silent! Like when you just roll down a hill (bike not running) all you can hear is the chain rotating. I let the clutch out and it started and stalled again, this happened about 3 times. Finally i had to pull off the road turn the bike off and on again and it was fine the 15min ride home. Ive only done about 200k's (155miles) on it and it happened. Im from Aus and havent got the Lag issue at all. Is there a fix or a known issue as to why it stalled? Spoke to my dealer and of course they've never heard of it so i figured this would be the only place i'd get an honest response??? For the people its happened to any advice would be appreciated! PLZ

NO quick fix yet, and yamiha hasn't issued a tech notice for it either. We are all patiently waiting. With my first ecu it quit on me twice while cruising in second gear at about 15mph and I blipped the throttle and it died. With the new ecu it's happend twice while decellerating. Seems to happen when I pulled the clutch in. Anyone else notice if it was when you pulled the clutch in?

Just wondering if there are any riders from AUS that have this stalling issue or any other issues with the 07 R1. I know the US bikes are different but anyoine from AUS have any issues???

WTF type of SHlTS is that. $11g bike and it's having stalling problems. I kept on thinking it was the servo motor. Is there a email we can just constantly spam for them to get it fixed?

The RPM for some reason drop's to low and fast and stalls out the bike. What I don't understand is why it doesn't do it all the time. I've told me dealer about it twice and both times they found nothing wrong with the bike. Grrr... :boom

I'm from Australia ;) here is a log i keep now of my stalling. Random Stall sometime in june or so it stalled 20 times in 1 night. Thursday july 19th 3 times Sunday july 22nd 1 time Thursday 26th july 1 time Friday 10th aug 1 time Friday 17th aug 2 times Saturday 18th aug 1time Tuesday 28th aug 1 timw wed 29th aug 4 times thu 30th aug 1 time It always happens when I pull the clutch in for to long. It's like instead of dropping to idal the motor cuts right out. Someone in this thread mentioned ETC (electonic throttle control) sounds like it might be it. I've noticed lately it seems to do it more often when i'm on last 1/4 tank of petrol. But i can't be 100% sure if this is a pattern, i've only noticed it in last 2 weeks. . But I am continuing to monitor it.

But I am continuing to monitor it. wow thats alot more than mine stalls, but thats a good idea to log it... think I'll start doing the same.

IF you actually pay attention let's say if you are downshifting, when you downshift your bike is already trying to die, it is just running on high rpm's lets say if you go to downshift from 5th to 4th, pay attention next time soon as you hit the clutch to downshift the rpm's drop so fast and you feel engine braking. Turn the bike on and down shift from 5th to 4th when the bike is not dying and you will feel no engine braking. They will not do anything until someone ends up dead. Mine usually likes stalling out Saturdays why I have no idea. Saturdays I ride hard.

Yeah I had the pcIII and everything on before and after the new computer, and it never died before. I got the computer changed for the lag issue, now I have this, Im not sure which is worse. And yeah I just unplugged the o2 sensor, and hasn't thrown any codes. I read somewhere that the o2 sensor only works anyways at idle at certain times, not really sure, but have no problems just unplugging

If you read this whole thread and other threads, you will see that the stalling shows up with the old ECU, with the new ECU, and with or without a PCIII and or ignition module. :fact

I really wondering how much importance the O2-sensor have, at least on my european bike cause on top of it all, there isn't any code24 (O2 status) in my diag menu (European). Of the things i tried to work around the problem nothing have made any difference at all, so adding your experience i can't think that the problem lies any where else then in program/ECU

I nearly came off when mine stalled :( Have you had any close calls yet?? I've spoken to about 15 different dealers in the past two days and only two of them mentioned it could possible be the TPS (throttle position sensor). Onle becasue of the 04/05 recall with the same problem. One dealer said only one of his customers mentioned the stalling to him and the others said they've never heard of it. Either they are all talking s@#t or no one is bothering to make a big deal of it, cause i refuse to beleive it is only 3 or 4 Aus R1's doing it.

They said they'd have a look lol. found nothing. So that's why I keep a log, when the holidays come i'll take the bike down with the log. They'll take a log more seriously then you just telling them it stalls. Must be something to do with logs and diaries are acceptable documents in law lol No close calls yet, but i can easily imagine it being a hazard. It's only happened when downshifting from say 4-3 or mostly 3rd-2nd, so when approaching lights or a corner. But yeah, thumbling around for the starter button and concentrating on riding with no engine power is a recipe for disaster. So what is the consensus here from mechanically minded people? Does it seem to be a TPS problem?

Ok so im taking my bike to my dealer tomorrow about the stalling issue and so help me god if these guys dont find or admit to a fault, because then that bike will be going up someones :secret: I'll keep those interested posted asap

So i took my bike back to my dealer today and told him about the stalling issue, he made one phone call to yamaha and within a minutes conversation im having the TPS replaced because that is apparently faulty, he has assured me that is the problem. But it is a rare accurance with the AUS bikes so all is well in the end. i think its happening more and more but most people arent bringing it to yamaha's attention, in AUS anyway. Only down side is getting the part here may take some time :eek:

my 07 has the stalling issue all the damn time. you start it and it stalls ten freakin times in a row but this is advice for all of you who want to buy pipes and a power com.. dont do it my bike has everything you can put on it and it still does it.:machinegu

1600 miles, no stall

I have said numerous times that pipes and a power commander have no effect on the stalling. They do however give the performance benefit that they were designed to for.

Yeah the pipes and power caommander ARE NOT designed to stop the stalling issue, they are made only to do what they are designed to do and that is to make these bikes haul ass. And they do do that. So yeah don't buy the pcIII or the pipes if you doing so just to correct the stalling issue.(They aren't supposed to fix it.)

going to take my bike to Loudoun Motorsports for them to fix my TPS sensor or get me a new one. Shit is really annoying stalling every couple minutes. Mine started stalling at 800 miles.

The reason for stalling is the TPS (throttle postion sensor) value is set to low. Take it to your dealer and they can adjust it. Mine works great now.

The reason for stalling is the TPS (throttle postion sensor) value is set to low. Take it to your dealer and they can adjust it. Mine works great now. I assume they adjust the value through the onboard computer that you can access through the LCD display. Any one know how and what numbers to enter? Would save me having to leave my bike at the dealers for a day or 2 or howver long it takes them to decide to get round to doing it.

In my opinion your best off getting it replaced, the problem is temperamental, so adjusting the TPS value might only be a temporary fix as the bikes dont stall every time you clutch it...

I assume they adjust the value through the onboard computer that you can access through the LCD display. Any one know how and what numbers to enter? I would so like to know how to adjust my TPS value through the gauge cluster.

Hell yes mine stalls!! I only have 10 miles on the bike so far(the reason for so few miles - no insurance, title, or gear yet) it only has been stalling in first gear. Lag time or not it sucks.

I quess so my R6 and two Harleys I had did't have that problem.:sing:

the dealer didnt tell me how or what he adjusted it to. i assume they dont want us to know...but then again i didnt ask. i read this thread and mentioned to him about getting it replaced, but it is only covered by warranty if it is toast...mine wasnt toast yet so he couldnt file a warranty claim. once the value is adjusted i dont think it is temporary... at least i hope not. maybe some TPS have been going bad since you have more miles on your bike. i got mine fixed at 385 miles.

My problem went away as of now knock on wood. I replaced my stock levers with Pazzo levers. I am assuming the adjustment of the clutch cable has something to do with it also. I rode this shlt out of my bike ever since I installed my new levers and hasn't stalled 1 time yet. Try adjusting the clutch cable near the lever and see if that fixes the stalling problem?

Hmmmm I am going to put more air in my tires and see if that works :lol Maybe it has to do with the drag co-efficiency :lol Seriously though, I doubt the lever replacement had anything to do with it. I am fanatical about keeping my clutch adjusted properly and I have still stalled a few times. It does seem have gotten better as I get more miles on the bike :dunno Even if the clutch was way out of whack, a downshift and a blip of the throttle should not stall the bike. As time goes on and after seeing where everyone is at with this thread, I am leaning towards a TPS issue. However it does seem, as I and others have reported, to get better in time as the bike gets more miles on it.

However it does seem, as I and others have reported, to get better in time as the bike gets more miles on it. Mines gotten worse with time. It used to stall once or twice per week, maybe bit more on a bad week. In the beginning i could go a week or 2 without a stall if I was lucky. Now it seems to be doing it every time i go for a ride for more than 20 mins. Since I use my bike as my main transport I can be guaranteed a stall every 2 days or so.

Mine is just he opposite :dunno weird...

Mine is just he opposite :dunno weird... Same here, I haven't stalled in weeks... I also doubt it has anything to do with it but I replaced my levers with Pazzo's and had adjusted my Clutch cable. It may be possible that helped... Don't see how though but hey I'm not gonna knock it.

Mine stalls a lot more now than it did when I first got it. I rode in a 200 mile poker run this last Saturday and the d*** thing stalled 5 times on me. I don't think it has anything to do with the levers as it doesn't do it all the time. If it was a mechanical problem(levers) it would be stalling everytime.

And if it was the levers/clutch adjustment wouldn't it kind of bunny hop a bit when stalling? These things just flat out die... Instead of the revs dropping to idle speed (1k) the revs just drop down to 0 revs and dies in the ass.

Like I said my levers and adjusting the clutch fixed my problem, but it could be the mileage on the bike. I did have sex on it also so it might of fixed the problem also.

I did have sex on it also so it might of fixed the problem also. It has nothing to do with the levers, it was the sex all along :yesnod I too broke the bike in right, with some fun with the wifey in a drunken stuper in the garage and as you know my bike has only stalled on me a few times and none since that time, now that I think about it. For all of you guys who are having the stalling issues, get your gal up or bent over the bike, and your stalling issue will be fixed. It is like a 2 for 1 deal :lol :secret: :sneaky :flex:

Hmmmm...... I'll get right on that.Lol

Hi guys, i have been om vacation for 14 days (without bike and internet) so nothing have changed a bit with my bike. About the most resent posts: First, i must say that my dealer have been very patient with my stalling problems, however, even though they test driven my first -07 about 250miles they had no problems with stalling, that was the bike they changed both the TPSs on and yet it stalled when i drove it. So they got me another -07, wich worked just fine... The first 4 hours, then it began stalling to, What am i doing wrong.. I really start to wonder? :confused: So, as much that i know, changing the TPS had no effect, disconnecting the O2-sensor made no difference att all, the bike run just as good (or bad) as before, no fault code either(?) I've been reading about readjusting the TPS.. Why do that? Well it could be that the ECU expect a certain "bottom value" which if going below (by temperature influence) the map will go out of range and cuts the engine.. Only a theory of mine... So, before i went away i advanced the throttle-TPS 2 degrees (making the ECU think the butterflyes are more open then they really are=richer A/F-ratio). The bike didn't stall but it still dropped idle to ~1000rpm now and then, and it obviously run richer which if it's a "running rich" problem should make the problem worse, but i can't say it did, however it was running rich so i readjusted the CO to -1. A new theory of mine is more that the problem get worse with higher ambient temperature, thats the really good clue i have right now. Edit:Okej, test run is done, and its NOT a temperature problem, drove for ~20min with ~15degr C and suddenly it just lost the idle when pulling the clutch, it kept bogging a couple of turns and then it worked alright again(?) As soon as the jetlag settled i will readjust the TPS to standard value and take a long testrun since normal daytime temperature is about 15 deg C (59F) here now a days (i really, really miss San Diego right now, haha).

Okey, now i spent some hours in the garage and got some news, haven't had the chance to test yet, it's to windy outside, however, i'm not to positive that there will be any improvement. First some clarifying about how the TPSs work on the -07: There are two of them, one for the cable pulley driven by the gashandle and one for the throttle valves. Now, for some reason Yamaha has chosen to put two potentiometers in each TPS, that can be for safety reasons or just as an extra backup, therefor ther's two values in the diag menu for each TPS. So this is what i done: First i reset the throttle-TPS to standard value (code1 and 13) to 16. Then i noticed that the value for the cable pulley TPS (code14) was a little bit low so i went in to diag mode, loosened the TPS and readjusted, doing that i discovered when going from 15degrees to 17 the butterflyes suddenly snapped open quite a bit (see images below), turning the TPS back they suddenly closed totaly, wow now that's something (i thought). So i tightened the TPS at 17deg, shut ignition off, turned it on again, butterflyes where closed... What? Okey, perhaps it moved while tightening, i loosened it and turned up to 18deg and they snapped open again, so i turned up to 19deg, switched ign off and on, the butterflyes stayed close, i did it all again and advanced even more, and it behaved the same(!?) With this information one can imagine that the TPSs resets them selves every time ignition is turned on, not the calibration value but its restpoints, therefore the exact calibration value of the TPSs probably isn't that critical as earlier thought. And suddenly the table shown below makes more sense (giving a pretty wide range for the TPSs). From now on i will stop focus at the TPSs as being the problem.

Wednesday evening took her up tp 9k revs, only ran it in last weekend, and everything shut down. No electrics what so ever. As I'm coasting along I turn off the ignition and then back on again and electrics restored. Hit the starter and away she goes. Have spoken to my dealer and they are looking in to this and will let me know when they have spoken to Yam. Also anyone had a problem with the outer frame bolt that clamps the teardrop shaped bracket to the Cat Canister? Mine has sheared off, I think it is a design fault as it appears to be under undo stress, wouldn't be suprised if this becomes a recall guys. Will keep you all posted on this one!

It is confirmed that the problem with these R1's stalling is definitely not the TPS! I got my bike back on saturday after being at the shop for two weeks, thats right two weeks (due to the TPS's being on distributor back order) :bs . I was assured it was the fix for the stalling issue, so me being all excited and the weather permitting i took her out for a short ride approx 50km! And of course to my surprise it stalled on me coming out of a round about and as i let the clutch out the back tyre locked up and slide out from under me almost causing me to come off. So straight back to the dealer it went. When i went back there he was dumbfounded and had no answers for me... Of course he couldnt ring yamaha to get a response from them being a saturday, so as of 8am this morning im demanding a new bike or my $$$ back! Its the second time this has happened to me and the second time i've nearly come off, This is absolute :bs and to think they have no idea what the hell is going on, I've just had enough of being the nice understanding customer :mad:

Something else is definately wrong with urs if its stalling while ur riding like that. I think most of ours are only stalling when coming to a stop and pulling the clutch in, not while we're riding and moving at speed. Thats scary if it just dies and locks up like that.

Your in need a rider course in your life. Good luck.

:iamwithst But on a diff note, why in the hell would you try restating or releasing the clutch in a turn?!?! :boom Of course your gonna slide out... Your in need a rider course in your life. Good luck. For starters i was already out of the round about gearing up to third when it happened, as i had the cluth in gearing up. I dont know how long it takes you to change gears :confused: but when your not expecting it to stall and let the clutch out as usual and the tyre locks up there's not much you can do!

Man, that's shite. This stalling is pretty dangerous. Everyone of my over 100 stalls by now has been in a straight line (lucky for me) but reading your post I can see the real potential danger of coming off now. My stalls have been like yours, it stalls so quickly at 1st you aren't aware it has died and you let the clutch out assuming your bike is still alive, when you here the back wheel lock up you then know its a dead dog. But lucky for me its mostly happened in a straight line. What if there was some gravel from road works on the road and the back locked up. You would be well and truely FU$#ED!!!!! If anyone is unfortunate enough to come off on these piece of shite bikes, sue the arse off Yamaha... My advise, keep logs of all your stalls, and use that as evidence in court.

I spoke to my dealer this morning and requested a refund or exchange in which he denied of course! Im sick of the response just be patient and leave it with me...Its not him nearly crashing on the damn thing. i also spoke to consumer affairs and am considering legal action for a refund or exchange if they dont give me results today. I didnt spend my $$$ on a bike for them to have it as their tester and really have no idea what is going on. I've kept logs on everything, i just dont understand how yamaha have no clue what the hell is going on with this s@#t and in the end its going to have to take someone to have an accident or worse for them to pull their fingers out of their ass.

What has your dealer said to you about the problem??? What have you done about it??? Any progress?

What has your dealer said to you about the problem??? What have you done about it??? Any progress? They had the obligatory concerned look on their face and looked the bike over when I had it in for the 1st service. Found nothing wrong. It's my only mode of transport so I have to wait till holidays before I can take it back to them. So unfortneatly for me I am stuck with this lemon. There is little I can do about it unless I am prepared to walk to work and back.

I just got off the phone with yamaha and to cut a long story short "be patient and they'll work it out" No replacement of refund, no ETA or fix just bare with them is the response i got. im over it i really am! This is bull S@#T

This is bull S@#T At least they acknowledge there is a problem, so there is some hope, they did acknowledge there is a stalling problem didn't they? What is the number you rang, I'll give them a ring too (I went to yamaha.com.au and can't find a contact number for them), The more people who ring and complain the better.

I contacted customer service which is in sydney 02 97570011 and spoke to a guy named jevillio (or something like that) a bit of a smart ass attitude. What state are you in??? cause im from vic and if your somewhere else you'll need your state yamaha rep details. You can get them from customer service also. By the way they didnt admit to their being a stalling issue, so i mentioned this site and told him to check it out and actually see that its not just my bike stalling, he probably wont though!!! He had the nerve to tell me to go ride with someone from my dealership to make sure it wasnt just me :mad: Let us know how you go :boom

He took down my details on the stalling issue and would pass them onto the engineers in Japan and see what happens. Other than that he was at a loss as to why it would be stalling. Which I knew would be the case, after all there's not much he can do. My reason for ringing was to log a fault with Yamaha directly. If only 6 people around the world log a fault then nothing will be done, if hundreds have then something may be done. So hopefully it just isn't the 6 people in this thread with this random stall issue lol Jevillio rang me back and said take it to my dealer and if they can't find the straight out fault then to tell them to ring him and mention the TPS, So my guess is at the very least they will swap that out for me But going by what jevillio said, your TPS being already swapped, and the guy a few post back Ozzian (who did the TPS experiments) the TPS doesn't seem to be the issue. I hope they figure out what the problem is :(

Definitely not the TPS im afraid. well my bikes at the dealer as we speak so hopefully they get a fix on it ASAP, im just annoyed because i dont want them using my bike as a demo for finding out the prob's. Really frustrating but shit happens i guess...

I rang Yamaha Scandinavia to hear if they come up with something since last time i spoke to them (~3weeks ago), this time i spoke to a new guy and he honestly said he had newer heard of the problem but he was very convinced that there are no problems they can't solve and he would contact my dealer direct. So i can just wait and keep my fingers crossed..... For you who actualy experience the problem, can you try to remember more exactly under what conditions it stall or the idle becomes ruff and lie at 1000 rpm or less?

This is just a hunch, but I believe there is a different issue with the US version than the Euro spec bike. We know this was the case with the ECU issues as it only affected US models. From what I have seen on here, the US spec bike seems to stall on deceleration, with the clutch in, or when blipping the throttle. The Euro Spec bike seems to stall on acceleration, and or varying circumstances. I think it is important when members are trying to gather information, that they understand the difference. The TPS fix seems to show promise for the US models, however apparently it has no affect on the Euro spec bikes.

hi,speaking about euro model I sell bike ....that's my job...and no one of the bike sold stalled...and in my group there are 4 people with these bikes ...never a trouble too....I don't know what to think but or.... here in Italy we are very very lucky (and we are not for sure:nforc:) or there is something different in the quality of parts that yamaha used to assemble the bike state by state...just for info here you can change the trottle end by using the diag directly just turning the key on and keeping pushed select and so on...then you can set minimum and a bunch of other things...

However, i got a tip today that seem promising but i want to try it out a little bit more before i say anything.

That was new, as far as i know the diag mode is not editable, just the CO mode.

That was new, as far as i know the diag mode is not editable, just the CO mode. I think her were referring to the onboard TPS adjustment :duno

My bike has done it gearing up from 2nd to 3rd gear and also gearing down from 4th to 3rd as soon as i pulled the clutch in on both occassions. My dealer has been advised by yamaha to check the fuel mixture and increase it (or something like that) because besides that they are lost for words and have no clues...If this fix doesnt work i'll getting the bike replaced.....enough is enough for me. :nforc:

No more stalling for me ever since I installed new levers. Woot Woot! weird yea but it did the work.

I thought we established that it wasn't the levers, it was the sex on board that fixed it :dunno

I thought we established that it wasn't the levers, it was the sex on board that fixed it :dunno the sex fixed it also, forgot to add. Just bored at work. Feels good when you no longer have the stalling problem :rock

I install'd my levers about a month ago and haven't stalled since. So laugh all you want. My bike no longer stalls, yours does. :sing:

I install'd my levers about a month ago and haven't stalled since. So laugh all you want. My bike no longer stalls, yours does. :sing: thats some crazy shit if you ask me..

I agree it is crazy, but 2 members have reported no more stalls with new levers. Is anyone still stalling after new levers?

I install'd my levers about a month ago and haven't stalled since. So laugh all you want. My bike no longer stalls, yours does. :sing: Just wanna ask a few q's about your stalling! What levers did you install? How often was you bike stalling and in what circumstances ie gearing up, down coming to a stop etc? Did you ever take it to your dealers and what'd they say??? Any help would be magic, my bikes been at the dealer for 3 weeks now and they said the bikes perfect...but still does it after the TPS replacement: no fault codes, it didnt stall on them, which obvioulsy it wouldnt :dunno finally! Did you move or adjust anything or change anything else in the process that may have had an impact? Thanks

Pazzo's... and I had to adjust the clutch cable, the turn screw is almost all the way out. Mine stalled only when down shifting, when I was coming to a stop mostly. But it had done it when going from 3rd to 2nd once or twice. That was a lil more scary cause I was doing about 20 to 30 mph. Dealer took it for a test drive and checked it out and found nothing. (Of course)

Why would the engine die just by pulling in the clutch? And if it was stalling because the clutch wasn't adjusted properly then you would feel the bike lurch a bit wouldn't you? I feel no lurching, the engine just flat out dies.

I don't want to be negative about the lever theory but my bike doesn't suffer only from stalling, some times, in almost the same circumstances, the idle gets ruff and sink below 1000rpm for half a minute, some times the engine stall, most often not, that could hardly have with the lever or cable free play to do, i think.

I had the stalling problem twice in one weekend, that was almost 950 miles ago, no problem since.....:)

Mine stalled 4 to 5 times, it usually happens when I am downshifting with clucth pulled in. It's very dangerous and frustrating especially when you're doing track days. I feel so much better now that I found this thread, I thought I was the only one having this problem.

I agree it is crazy, but 2 members have reported no more stalls with new levers. Is anyone still stalling after new levers? i have pazzos on my bike and i still get the stalling problem every now and then... i noticed that its usually when im coasting with the clutch pulled in ( i live on a hill so somtimes i just let it roll down and this is when it happens mostly) other times its when im splitting traffic on a freeway shifting from 1st-2nd and back to 1st.. the problem only happens when i engage the clutch in first gear.. another thing... once my bike stalls no matter how many times i start it back up it will just die again.. the only way for me to start it back up is to turn the key to the off position and turning it back on and then firing it up.. then it will stay on.. so im guessing its an electronic problem... something where the computer has to be reset..

Thats what happens to mine when it stalls, i have to stop and turn the bike off and on again otherwise it just bogs out and keeps dieing until its reset. Im lost on this one, my dealers assures me that when something like that would happen it will come up with an error code on the display. Its frustrating to know it happens but not be able to show him ...

Sounds crazy but is there anyway to get it to the dealer before you reset it? With it happening over and over again, maybe he could send somneone out, if you were close enough to pick you up with the bike. I realize that leaving the key on will drain the battery in no time, but how else are you going to let the dealer test it while it is in that state?

That would be the perfect thing to do but im sure when its happened there's been no error code or anything on the display? Can anyone on this thread verify that? When the bikes stall has anyone had any msg's on the display about a fault or anything at all to indicate something was wrong???

I agree there is no code when it happens, but if the dealer could see the condition when it will not re-start, they can verify it, and at least understand that you are not crazy. Plus lack of an error code on the display does not mean that the computer at the dealer would not pick up on one.

My dealers done every test and checked the bike from top to bottom and test ridden it and said the bike is coming up as being in A1 perfect condition, my only hope is that it stalls when they are riding it, in the mean time we seem to be going around in circles........and i look like i dont know how to ride...

On older bikes you have an idle screw which physically sets the idle. On these bikes there is no idle screw so it must be done electronically. So what electronic part is responsible for maintaining a constant idle? These bikes seem to have the Monopoly syndrome (Do not go to idle, do not enjoy a bike in momentum, but go directly to 0 revs and engine stall) As I would say that part is the culprit. Just to give a brief outline of my stalling, I have noticed that when its due to stall, i hear a noticeable difference in the sound of the exhaust. Usually the exhaust sound is quite and non impressive from a riders point of view, don't know how it sounds to people I pass ;) But when it's coming to stalling time my bike starts to get a beefy rumble sound i can hear quite noticeably from the rear when I'm engine braking. I actually like the beefy rumble it makes, but sadly it dies soon after.

Only one time when i restarted it kept dieing 5 times in a row, otherwise it always restart but have a little ruff idle for 5-20 seconds. About idle: There is no separate idle circuit in that manner, since it utilises FBW throttle the throttle motor sets the idle , if the butterflyes close fully allmost no air will pass. There is, however, one air bypass screw on each throttle body to performe the syncronisation, but it's not really used to set the idle.

Yeah me too, I just hit the starter button and it starts straight up again (I don't have to turn the ignition off then on again). Mine tends to either stall just the once or a series of 3 stalls in close succession, then things will be fine until the next stalling cycle which will usually be a few days later.

i have pazzos on my bike and i still get the stalling problem every now and then... i noticed that its usually when im coasting with the clutch pulled in ( i live on a hill so somtimes i just let it roll down and this is when it happens mostly) other times its when im splitting traffic on a freeway shifting from 1st-2nd and back to 1st.. the problem only happens when i engage the clutch in first gear.. another thing... once my bike stalls no matter how many times i start it back up it will just die again.. the only way for me to start it back up is to turn the key to the off position and turning it back on and then firing it up.. then it will stay on.. so im guessing its an electronic problem... something where the computer has to be reset.. You my friend have a totally different problem, I would take that bike to the dealer and raise some serious hell.

Why would the engine die just by pulling in the clutch? And if it was stalling because the clutch wasn't adjusted properly then you would feel the bike lurch a bit wouldn't you? I feel no lurching, the engine just flat out dies. I'm guessing because the rpm's are drop'n to fast and to low and kill the engine. I've asked them to adjust my idle but they said it could'nt be done. (Bullshit I say) And no, I feel no lurching. PS. I rode all day today and still no stall's. Bike now has 2400K miles.

IMO on a regular clutch lever, I ride with the lever real loose. I like for it to engage as near as possible to the clip on. I guess when I had the clutch lever adjusted that way it was some how cause the bike to stall. After I installed the Pazzo's I haven't stalled since. It might even be the switch behind the clutch lever that might need to be looked at. When installing the Pazzo's you now are adjusting the clutch lever with teh silver know and the lever on the pazzo. Haven't stalled since 8/31/07 :rock:

I think I am getting it now, I believe that some people were stalling from a mis-adjusted clutch, that seems to have been corrected with the install of new levers and properly adjusting the clutch. To me the 07 seems to need the clutch adjusted perfectly. I probably adjust mine on every other ride. I will be at a stop or rolling with the clutch in, and blip the throttle, I can actually hear the clutch tap into engagement, and a slight surge. When the happens I know it is time to adjust it a couple of turns. I am also probably more sensitive than most riders to the feel of the clutch. Carnag3 R1 said that he rides with his clutch real loose, it calls for very minimum free play and certainly not enough to be close to the clip on. This whole thing clicked to me when Str8Evil told mypantsaretorn that his problem was different. I know my stalling and several others on here have reported the stalling tendacy exactly as mypantsaretorn described.

Like my clutch lever when it was stock I can pull the lever in and it wouldn't engage until right at the end, I like my clutch lever soft. Went to pazzo adjusted both levers and knob and works. Hopefully this fixes the stalling problems? The owner before me said he never had any stalling problems on the r1. I bought my R1 with 800 miles from him. He had the clutch lever adjusted so as soon as you pull it in it engages. Which has a harder feel.

I usually keep my clutch levers with about an 1/8 inch of play depending on the bike, sometimes it can be a little more and sometimes a little less. If you can pull more than that without engaging the clutch than a new set of levers with proper adjustment would resolve the stalling problem you were having. The problem would have been dragging the engine.

I rode all day today and still no stall's. Bike now has 2400K miles. that is bullshit, did he say that with a straight face? seriously..

my bike stall on me and i took it in to the dealership and they replace a divice on the clutch side of my bike. i thought that was then end of stalling. Untill to day i was ridding to my girls house to drop her off and we spliting lane on a main street. as soon i hit the intersection it stall on me. then i try to restart it but it wouldnt start i was rolling throught the intersection around 2mph and car were passsing me. it really suck. i kept tring to start it. it would start then sut off. i pull over to the side and try to start it but it would start up. so i held the gas and start it but as soon as i let go it would stall. then i trun of the bike and staring cursing. i was like this shit really sucks ass. then i turn it back on and it start. i think It is while stopping and it has only happened when compression braking and then shifting down RPMs drop to low and it dies. i really need help with this cause i dont want to laid my bike down

try adjusting your clutch.

Mine just started (at about 5000 miles) stalling when I hit the clutch at higher RPMs, like stopping quick for a light.

I'll be filing this away under the WTF! files. I adjusted my clutch (I had nothing to loose even though the idea seemed ridiculous), low and behold my stalling issue has gone :dundun: WTF! How bizzare.... Well it's only been 3 days so far and no stalling, I'm hoping I haven't jumped the gun in my celebrations. But it even seems to idle better. Before when the stalling issue was about to arrive, when I would pull up at lights and in neutral the idle would be ruff, like it would jump around from above 1k to below 1k then I would be sure of a engine cut out a few minutes later when I pull the clutch in. For the last 3 days it hasn't idled bad or even hinted at stalling. So knock on woood, my engine dying has come to an end... I'll keep you all posted if my good fortune holds out over the coming days/weeks.

So **** it I'll take it. =)

Okay I don't really wanna read nine (9) pages of thread. I'm looking to get the 08 R-1. But I was thinking if there are any 07's leftover and their giving it away to make way for the 08's. Is it worth it to get the 07? I hear about this lag issue and now this clutch problem. Would I be better off going with the 08? 07 owners let me know what you think. Thanks in Advance

MY theory was correct :rock about the clutch adjusting.

A properly adjusted clutch will affect stalling on any bike, perhaps the 07 is more sensitive :dunno However there is an occasional stalling issue on the 07 that seperate and distinct from the clutch problem. :fact For the what to buy 07 or 08 poster .... they are the same bike, so it really doesn't matter, just make sure if you get the 07 that your dealer installs the corrected ECU before delivery.

MY theory was correct :rock about the clutch adjusting. I thought it was my theory... hmm... lol

I thought it was my theory... hmm... lol :bow: I'll take east coast you take west coast.

weird, i have this problem too... stalls on me sometimes 8 mph or less then i quick rev it, dies.

Havent heard anything in this thread for a while... has anyone still got this problem after you've adjusted your clutch? I thought this issue was over and done with.....

it was. I'm tryin to sell my R1 now :)

Wow my 07 has stalled probably about 10 times a month, I'll give the clutch adjustment a try... but where should it be set to? Right now, I have to pull the lever in about 60-70% (100% being the lever touching the grip) to disengage. Any thoughts?

Clutch adjustments are based on the amount of freeplay in the lever. In other words how far can the lever travel from the perch freely. Your manual gives exact measurements, but the rule of thumb, is that you need a small amount of free play, enough so the clutch can fully disengage when you let it go. The 07 does seem much more sensitive to clutch adjustments than previous years.

I bought a new 07 earlier this year, I soon realised that once the engine reaches 100 Celcius and you get of the throttle quickly it cuts out when you stop hence it doesn't Idle. No Stalling in rev range (damn good thing) but it was a bit annoying. As soon as I pop the clutch and give throttle it started up again, so I compensated for a while by timing lights and applying a bit of throttle when coming to stop. The throttle was a bit jerky but it was a new bike and I thought it was my eager wrist. Anyway, I put the first 1000km's on the bike fairly quickly and the dealer sorted it out with the first service. I also had GYTR slip ons installed at the same time. So since then no proplems. She is furious and screams like a bansheeout of hell. Did anyone else have his idling issue ? Ride safe and respect the beast :fork

my 08 stall for the first time yesterday....damn it.... stall for 2 times, turn the key off and on and start again no problem.... im guess no answer/fix to this stall problem....???????

Your Yamaha agent should sort this out for you, we received a bulletin explaining that the air screws needed to be turned out 180 degrees, and then balanced. I have done this to my 07 and many other 07 and 08s, it works like a bomb. The problem is insufficient air in the throttle body (too lean),which causes the bike to stall when coming to a halt with the clutch in, and in a few other circumstances. The procedure is simple, make sure idle speed is between 1250 and 1350 Rpm, turn the white painted air bypass screw out 180 degrees ,turn the other screws out 180 degrees, install a vacuum guage and balance all screw so the reading is 20Kpa in each cylinder.

Take it to your dealer ! :hellobye Beasty ... I see your from SA bro ! from where ?

Im the Workshop Manager at Linex Yamaha Randburg

well, i figured out why mine was stalling, the chain was a tad loose(initial stretch at only 100 miles....put your chain in spec, and clutch lever in spec, problem gone!

Im the Workshop Manager at Linex Yamaha Randburg :thumbup Cool man ! I am in Centurion PTA ... will be back in the country on the weekend and I'll try to stop by sometime. Will start an official SA rider thread in the next two weeks. :hellobye

You can try,lift tank and look with a torch at bottom of injectors facing the rear of bike.You will see a raised channel with a 4mm brass screw in it.The "master" has a white paint mark.Turn it and all the other cylinder screws out 180, it will already be better.

I had the "screw turnout" done here in sweden and they did as you described, but they also put a thin shime between the TPS and the throttle body, is that something you heard of and why would they have to do that?

hey please let me know how the result..?? is it better or still stall...? Hi Since winter struck Sweden... Again (it comes and goes, strange winter this year), i have only had a few times to test it with the new adjustments. As some more have mentioned it usualy stalled after driving for an hour or so, so i think it's partly a heat related problem (in my case) but it have stalled a few times in shorter time too, main factor (as i recall it) was that it happend when out door temp was higher than it is now so i'm not convinced yet. I'm still pretty sure the adjustment is more a patch to the problem than a real fix cos it still looses the idle under the same circumstances as it earlier would stall, only it can't go so lo making it stall, but as i said, it's still rather cold here in Sweden, only time can tell.

hey thanks beasty... i try to lift the tank, and yessss...i see the 4 screw u talk about...the most left is the white painted screw...BUT look like its hard to turn the screw coz no space available in front of the screw for put the screwdriver in....maybe i need a small screwdriver.... one more qyestion, if we turn out the air screw, does it affect the performance of the bike since we let more air in to the cylinder (im guessing)...???? No,performance is no better or worse,its only getting significantly more air on idle.You do need a short thin flat blade driver though.

I had the "screw turnout" done here in sweden and they did as you described, but they also put a thin shime between the TPS and the throttle body, is that something you heard of and why would they have to do that? Sometimes the seal on the TPS can get sticky and not allow it to return to the zero position,this causes the mixture to be too rich at idle and hence stalls,I would presume that the shim is helping this,although I have not experimented with this shim mod.

No,performance is no better or worse,its only getting significantly more air on idle.You do need a short thin flat blade driver though. ok if no performance affected, tonight i will buy a thin short blade driver.... tommorow is the time for turn it out... turn out= turn left=anti clock wise right...????

Okey, then Yamaha here in Scandinavia didn't take a chance (since i've been a real pain in the ass) so they did all they could think of to, hopfully, hit the weak spot. One thing i like with adding more bypass air is that the engine brake got a little milder :thumbup suck to hear about the winter brutha... hope everything get clearer soon.... Thanks, well usually ther's much more snow this time a year so it's pretty good cos some days when the winds are warm it's "driveble" so it probably (hopefully) be an early summer :) Hope you get some improvement with your bike bro cos this stalling thing sucks.

ok if no performance affected, tonight i will buy a thin short blade driver.... tommorow is the time for turn it out... turn out= turn left=anti clock wise right...???? Yip,anti clockwise 180 degrees

Yip,anti clockwise 180 degrees Thanks for that info...you never mentioned the sensor that is hooked into the hoses that fit to the TB. i used the carbtune 2 for the balance, hooking up the sensor with a tee. :)

Thanks for that info...you never mentioned the sensor that is hooked into the hoses that fit to the TB. i used the carbtune 2 for the balance, hooking up the sensor with a tee. :) yep tried that to been in the shop 4 times trying to fix this issue

i have turn out the air screw.....tommorow will give it a try....

today ride for 100km......no stall found.....hope the air screw tuning really works well...

subscribed

subscribed just do the screw turn Steve......its easy and if the turn have no improvement, u can easily turn it back to the previous position...:)

Nope...never had this issue and didn't even know it existed until I saw this thread.:confused: I hope my luck continues but glad this thread exist in case mine ever starts havingthis issue.

Mine is really strange, I dont get it. Listen to this...... So when I ride with my girl I take it nice and easy, dont rev the bike past 5/6k rpm you know just nice and soft (at least most of the time) and it stalls when down shifting. Also it seem to do it more when its warmer. But when im riding alone and beat the sheit out of it its fine, not a single stall. WTF

lift the tank....there are 4 screw facing rear of the bike, its located at the bottom of injector....the most left is the master screw which painted with white mark/paint.... turn it 180 degree out (turn anticlockwise)....do it to all 4 screw....thats what i did 5 days ago, and no stall after that....try it....it cost nothing, make sure u use a small and thin screwdriver...good luck

I don't even give the dealer a chance to screw me. When I bring the bike in for service and warranty work (mine stalls too) I remove the PCIII. It's a pain but I can remove/install in about 20 minutes. Small price for me considering the alternative.

I realize that the power commander has nothing to do with it, it did it before I installed mine as well. Its just the dealers around here are well known for poor service and Im afraid if they just cant find anything they will charge me for it... Has anyone done the balance of all screws with a vacuum gauge themselves? Is the vacuum gauge they use a standard tool that I could pickup? I was at Sears and didnt see anything that measured low enough.

Ive never had the stalling issue on mine. just the 2nd gear lag

Well I did this last night and Im pretty sure it fixed my stalling. No stalls during the short ride to work but I can definitively see a difference right after starting. The idle is much more stable and the RPMs dont bounce around like they used to. Do you think its worth it to take into a dealer and have them do the pressure balancing etc or is just turning the screws good enough?

Here are a couple pics of the screws, the painted one and the other in the middle I could not get a picture of however they are all in a row. You will see small silver tubes with a screw on the end extending out towards the seat.

Alright, Im a tech at a Honda dealership in texas that is havin the same problem, mines an 08...yosh carbon fiber slip-ons...pc III dyno tuned...AIS mod...and bmc air filter. The random stalling started about three months ago, very few and far between, but here recently EVERY SINGLE TIME I RIDE..without fail...it stalls after i get off of high rpm's (higway riding at 70+). If it doesnt stall immediately after i pull the clutch in to downshift, it goes into a rough idle and falls all over its face and then stalls. When I hit the starter, it fires up again with a weak idle (below 1k), and if I make any attempt to blip the throttle it dies again. Then, once i start it and leave the throttle be, after about 8 seconds it works its way back up to the norm between 1200 and 1300. Now, all that being said...havent tried the throttle body sync screws, but ive tried the exup adjustment, the clutch adjustment, and thought a dyno tune would help but none of the above has done a damn thing...:banghead: The way it idles when im done hauling ass leads me to believe that its revovles around fuel management, it did the same thing prior to my pc III and my tune, otherwise it wouldnt idle like its cammed out and it wouldnt die with any throttle. Any one have any more pointers or ideas for me to run with? Taking it to a Yamaha dealer and getting screwed around for a month for them to get Corporate on the phone, much less the same page, is the last thing im planning on doin.

Alright, Im a tech at a Honda dealership in texas that is havin the same problem, mines an 08...yosh carbon fiber slip-ons...pc III dyno tuned...AIS mod...and bmc air filter. The random stalling started about three months ago... Any one have any more pointers or ideas for me to run with? T This "bug" has been discused in some more threads here at the forum http://www.r1-forum.com/forums/showthread.php?t=227340 I'm pretty convinced it's a software problem of some kind causing the engine to stall. Sorry bros for sounding like a scratched old record (i have probably allready written this some where in these threads). Here we go: Last year i hooked up some multimeters to read the voltage from the throttle TPS and the O2-sensor, what i really wanted was to log the measurements but had no equipment for that. Of course the bike quit stalling the same moment i attached the multimeters.... (damn Murphy.. hehe). However, it still lost its idle as previous and the readings showed that the throttle then was more closed than during normal idle. So the managementsystem did nothing to compensate for the low idle, it even worsend it by keeping the throttle more closed and that's probably why the syncscrew adjustment works, you flush through more bypass air so it doesn't matter if the butterflyes are "to" closed. In my opinion not a fix, just a patch to the problem. So what could be the source of such a intermitent problem, the O2-sensor? Sadly i didn't know at the time how the sensorsignal worked so just reading the voltage from the sensor with a common multimeter doesn't give that much info. At DynoJet i found a "O2-sensor remover", not for the Yamaha but for other brands, i found out that when applying a PC3 to the R1 you often just disconnect the O2-sensor and leave it out. Curious about that i started look for the sensor values and errorcode in the bikes Diagmenu and found nothing, not a trace of any O2-sensor being attached(?) So i disconnected the sensor but it made absolutely no difference what so ever, no errorcode, the bike went as (bad) as before, maby its funktion is not used on European bikes? What i will try is a tip i got in some of the related threads, let the bike adapt to idle. I have disconnected the battery for a while, put it back and started the bike and let it warmup without touching the throttle, and the same every time i go for a ride (well, not the batterything). A related thing is that sometimes i felt the bike lost some power in the lower midrange, by a coincident i found out that by just pulling the clutch (while driving) and turn off the ignition for a couple of seconds and then restart would kind of "reset" things(?!) It works even when the idle gets rough, laying around 1000rpm, bogging, just turn off and restart... 1200rpm instantly!

I just spent $140 at the dealer for them to look into this issue. $70 an hour!!! Apparently warranty work only applies if they find something wrong! I bought 2 bikes from these guys last year and am still getting bent over. I'm going to start building my own bikes, at least I'll know who to blame when they take a shyte in the middle of the road.

They really know how to weasel their way out of things. You know, i'm starting to feel the same as you. Of course Yamaha should earn money, no problem with that and i'm not out for a win, hell i'm just happy to "break even" but as you said, recently i'm not happy with how things worked out and if they do it's because i had to put so much own effort and time (and some money) in to it and allways feel like a royal Paine.I.T.A to the dealer... My first two R1s worked like clockwork for the 80k and 40k miles i had them, perhaps it's just my time to take some shit :drunk:

man....just do the screw turn..it works well...no stall at all, i think thats what we can do for now....looks like yamaha cant fix it... today is a week since i did the screw turn, i dun care its a patch or a fix, the most important is now my bike not stall again....temporary rough idle is not a big problem...now i never worry when do up/down shifting.....

Not really questioning the theory persay, but i am curious as to how turning the screws keeps it from falling on its face when coming off the highway, but doesnt stop the rough idle?:dunno

Alrighty, update time...took it to Central Yamaha here in dallas, where one of my best friends works. Had him pull the tank off; showed him where the screws were, and he spun them 180 degrees. Put it all back together and took off down the street, and it died at the first light. Keep coming up with ideas, and ill keep being the ginuea pig. Im up for whatever at this point, because nothings working.

time 2 trade my bikes been in the shop 45 days since oct 07 hondu or a gixer sure does sound good now even harley dont have this much issues:rant

even harley dont have this much issues:rant :lol:hammer::crash

Aside from the fact that it stalls, and thats gay...dont get me wrong. I dont have a single other complaint about my 08. With yoshi slip ons, a bmc, a pc III, and an AIS mod, im sittin at 171 to my rear tire.The only thing that ive managed to be beaten by thus far was a 1200hp (to the ground) C6 Corvette Lingenfelter. Even then it wasnt an ass beating :finger. Im not ditchin Yamaha quite yet, been ridin em since i was 5... So im just gonna wait patiently, until someone comes up with a fix. Until then ill just keep hittin the starter at every third light.

I don't know what to think about the -07 R1 any more.... Yesterday it was fairly warm so i worked half day and went for a ride. I tested what i wrote in an earlier post: Not touching the gas before the engine fully warmed up, so i did. The bike was really wonderful, no loosing idle and it pulled fine from bottom and up, it even felt less "digital" in the area between off and on gas. Sometimes the idle was a little bit high when stoping at redlights, it have never done that before. So i went for ~230miles, stopped for gas and went for another 160miles. Stoped at a friends garage and left 1,5 hours later. Ones again i let it warm up before touching the gas but now the bike wasn't the same, it was a little bit twitchy when giving gas from idle and didn't pull that well in the bottom range and sometimes the idle went down a bit. However, it didn't stall ones :)

Soooo.. Has a "absolute" fix been figured out?

This is really disappointing for me being my first yamaha, I cant believe that yamaha hasnt had a fix for this. Im pretty sure they are aware of it, also the whole rearset thing braking by its self, what kind of BS is that? I have never seem a bike with so many issues right outta the box, not even GSXR's

I have never seem a bike with so many issues right outta the box, not even GSXR's thats what i think at 06, then i bought a gsx...and after ride it for 2 days, the clutch start vibrate like hell when i launch the bike hard, gsx forum tell me that something wrong with the clutch washer....and i found that gsx k6 has frame problem which scared me....theres a k6 with no wheelie, no accident, has several hair crack on his k6 frame....damn...ended with sell the bike and get an 08 R1.....and now with 08 R1 i found this stall problem...... but my stall fixed with screw turn.....:) i think every bike has their different problem....no perfect bike

And to be honest they are not slow, maybe in the straits. If the freaking 08 wasnt that ugly i would have one by now

I had absolutely no problem with Honda. And to be honest they are not slow, maybe in the straits. If the freaking 08 wasnt that ugly i would have one by now yes...agree..if 08 cbr is not that ugly (the front end), maybe i ride honda now....

I had absolutely no problem with Honda. And to be honest they are not slow, maybe in the straits. If the freaking 08 wasnt that ugly i would have one by now Hahaha IMO that bike is f&%#*!n ridiculous lookin, we just got like 50 of em in to sell this month, and we have put two out the door. Quite frankly, you couldnt hand me the keys to that thing...its been said in reviews that it puts 171 to the ground out of the box...:bs: My general manager rode it after i put a pipe on it and we had a drag race from 0, a 40 punch, and a 90 punch (he used to road race professionally for honda)...i have 170, and it was like i was racing a 600. Granted it doesnt stall and it handles a little better? lol However, its ugly as hell and its definately not the fastest thing on two wheels.

No problems with either of my Yamahas nor my 2000 R1 I used to own. No problems with 3 Kawasakis or 2 Hondas that I've owned. I hope luck stays with me. These stories suck but I'm subscribing in case I have issues in the future. To everyone that is having the stalling issues... 1. Are all 08's having this issue ? 2. On the 07's with this issue...did you have the 2nd gear 5500 rpm issue fixed ? The reason I ask is I wonder if the "07 fix" contributed to this issue...which would include all 08's ? 3. I never had the 2nd gear 5500 issue addressed because it never bothered me on the street and my bike has never stalled...just a thought. It has been mentioned that this could be a "software" issue is why I had these thoughts.

The stalling issue has shown up on 07's with and without the ECU upgrade. I know this because I personally followed the ECU issue very closely.

I just was wondering...I didn't see where it had affected 07's without the ECU upgrade but wasn't sure since I just learned of the stalling issue...thanks.

..... i think every bike has their different problem....no perfect bike -05 R1, that was my "perfekt" bike, sure there was this TPS thing, witch never gave any problems on my bike but it was changed on the recall, no problems with that bike at all, i allways did what it should without any fuss. Of course, when the -07 behaves like it should it's so much nicer than the -05, but you just can't count on it.

Mine's been pretty good the last few rides no stalling and i never really had the rough idling. Maybe mine fixed itself :finger it seemed to just get better over time...

Hey Ozzian looks like things may be looking up for you now! its good to hear. Mine's been pretty good the last few rides no stalling and i never really had the rough idling. Maybe mine fixed itself :finger it seemed to just get better over time...Definitely XITNU, for the last two rides it has been on it's very best behaviour, and with a new set of tires it's an awesome bike :) Maby it's a combination of that adjustment and some extra "break in" time but i'm allready up for the 16k service so i think it should be pretty good "broken in" by now :crash Another thing i've done is to tighten the throttle cables to a minimum of freeplay, that way it's easier to quick "pick up" from fully off throttle. Good to hear things has worked out for you too.

Hey, guess I'm a little late in posting on this thread, but I've had a nightmare with this on my UK spec 07 R1. I got to the bottom of it with a race mechanic who dyno'd my bike. The two throttle position sensors were well outside their operating tolerances. One by 5 points. I'm still waiting to get the other adjusted. It's a bitch as it requires the removal of the injector bodies. I've not got time to mess around trying to get Yamaha to accept and fix the problem
