Well here it is, I got my brand new 2007 R1 and with less then a 100 miles on it. Yesterday, I took it out for a ride, and now right at take off it misses! But it seems to clear up when the RPM's rise. Now its back to the shop for the R1 !

this is a new model bike (not a complete revamp, but some significant changes like throttle control, and # of valves, and other electronic bs, etc.) so i would expect it to have a few problems,

and not every 07 R1 is having this problem and if they were BIG DEAL, every manufacturer has lil problems and it in no way reflects the quality of the brand and not just bikes, first year cars and trucks go through a year of bugs to get worked out

and as good as Suzuki has been to me there were problems and lil bugs with some of the bikes in the GSXR line-up years ago just like all other manufacturers,
and you couldnt pay me to own another junky Ninja:dundun:

nothing against it and before you say it NO im not stirring things up. but everyone of these posts about somebody having problems you try to say its them not being used to fly by wire, their shouldnt be any getting used to it. if its working properly you would never know that its fly by wire.

and i dig the r1's thats why i hang out here, not being a troll... just cracks me up reading your posts defending it...lol

My old neighbor got a new blue 07 for Christmas and it did the same thing. It was 37 today and a bit rainy later on but he was out riding and came back after like 30 minutes and said it was lagging on him big time. We put it up on my stands and revved it up and I didn't notice it. He took it out again and said it did it again. Going with him to the dealer tomorrow to see what they say. I feel bad because I told him to get a Yamaha R1 since I have had nothing go wrong with mine. He's talking about just getting the Suzuki instead.

Defending what!? If we had a problem, dont you think we'd fill you in? i have not had a problem as of yet, and dont see anybody complaining about shit, Now!! It sounds like everybody wants the 07 R1 to fail.............They have sooooo many vehicle w/ FBW now, you sure the hell don't here about problems w/ GM and there crap!!! TPS, only lets you computer know were the throttle is @!! Closed, Open,WOT, thats all!! It has a built in feature in case of failer, that will let it operate in the event, something wrong!! Missing does'nt mean shit!! And it certainly is'nt a TPS issue!! Get a FY%$ng brain!! You think Yami would stake rep on a faulty system design? Don't let them hear it, they may own your ass!! (And yes, NOT contradicting myself)They may have a few problems, who knows, but trying to whack their balls is OFF center, BAD!! I wont even begin to tell you all that, any TPs issue comments are B.S. Its a potentiometer, guys, WTF!!! I, have NEVER seen a vehicle yet, produce an issue like descibed, on anything!! Maybe a Jeep, but it did not miss..............And, The trouble code was'nt present by the auther, solid or intermittant. Can someone justify this thread??? Please, let me know, I have AMA Pro racer Tech. freinds,that would like to know. We have a late model R6 w/ FBW, and although it had an early on problem (from what I'm told) Has'nt had a problem yet. 0-172 multiple times and guess what!? NOTHING!! I just got back from riding my R1 w/ less then 1K on it, and all I can say, is that I've picked up @least 10 HP. Feel free to let it fly, I can get to the truth of this rumer, just let us know the minute you find out what a dealer has to say about it! Maxx - Out

You think Yami would stake rep on a faulty system design?
No manufacturer is perfect when it comes to working all the bugs out of a brand new system. A recent example is the new FZ-1. It has a well-documented problem with its fuel injection mapping.

Also, no manufacturer is above being dishonest about certain things (remember the false claim of 17,500 RPM on the 2006 R6.)

So, it would not surprise me greatly if they released the 2007 R1 knowing that there was a YCCT problem in an effort to get it to market faster. They probably just intend to provide the dealerships with a fix.

There is no question that at least some of the new R1's have a problem of some sort with the YCCT. This many people can't be wrong. I have one (#874) that I bought on Dec. 15 and have put 949 miles on. It took me about 500 miles to get used to the slightly more abrupt response of the YCCT, mainly in regards to being able to shift smoothly. I've just learned to be more precise in my shifting, and now I am shifting more smoothly than I can on my '05 R1.

However, it is clear that my bike is one of the units affected by the "throttle lag." Not to mention the "soft" response at lower RPM, and the excessively long twistgrip travel (by the way, the long twistgrip travel has been noted by at least one major industry rag during track testing.)

I will try to describe the problem as best I can:

When attempting to re-open the throttle in 2nd or 3rd gear at the apex of a corner to attain drive out of the corner, there is a definite, perceptible hesitation of about one secondbetween my rolling the twistgrip and the YCCT obeying my command to open the throttle. After the delay, the system begrudgingly and slowly acknowledges my demand, and gradually opens the throttle. A point of note: this delay usually happens when I'm out riding curvy backroads, and usually happens in a corner where the moment of closing the throttle and the subsequent opening of the throttle are relatively close together. In a corner where I'm spending more time braking before reaching the apex and rolling the twistgrip on, it usually does not happen.

It's a quirk. It doesn't happen on every corner. But again, there's simply no question of if it happens. The only question I have: Is it a software problem or a mechanical problem. What's the fix? I plan on taking it back to the dealer soon to have him look at it. Matter of fact, there's a guy on this board (southern118) who works at the dealership where I bought it.

A question for some of the guys who have 2007 R1's: What kind of riding are you doing? Reason I ask is that the couple of times I've ridden the bike to work on the interstate and on city streets at mostly steady state cruising and steady throttle, I haven't noticed the problem......seems to happen out on the backroads when I'm riding more aggressively in the curves.

And, like I say, I don't consider this to be a huge issue. It's a minor irritation in comparison to how great the new R1 is overall, and I fully expect Yamaha to address this issue expediently. They are bound to already know about it, and I'm sure they are readying to alert dealerships to the fix.

Sorry for the long post, but a serious situation demands some serious thought.

:corn

You guy's can slam it all you want and if I had any issues with mine I would be the first to post it up.

It runs great.

I really don't consider 5 or less people having a similar problem an issue, when all of there bikes are new and they haven't even ran one tank of gas through them.... My suggestion to a couple of them was to run a couple of tanks of gas through it and see what happens. I have not heard back from either one of them that said they would do just that.

Anyway... bash away, but this is clearly the BEST R1 ever built.
 
#24 ·
I'm calling tomorrow to see what they say. The fuel light just came on yesterday, but I have not put gas in it yet. This issue is just at idle, then when I take off from a stop it missfires a bit then seems to clear. But don't get me wrong guys, I am not bagging on the bike at all. Just wanted to post a problem I encountered. I will post what the dealer says tomorrow, but I am almost thinking it might be one of the coils because I can also hear a ticking noise at the same time. Well, I will ost more as soon as I know.

I've got 700 miles on my 07 And It has been GREAT.. But I can Tell you this,, The Cheap B@stereds at the dealer filled it up with Regular Gas.. Oh Yea.. Spark knock a few tims on Easy take off's...I was ticked aboutit And It did Hesitate on take off.
Also, The people who posted about the PCM havin to learn ( ARE So True) You have to got threw a few " Drive cycles " Before it learns all of the features ofthe bike.
But Keep us posted . As I am Curious... Not even worried.

Unless you get me some sort of definitive proof on that, I'm calling BS. There's no fancy system in a motorcycle "learning" from the rider. It's just a microprocessor reading sensors and acting on those readings to control fuelling, exup valves, etc. There is no "run in period" for a motorcycle ECU.

Jeez . . .

Its all part of the new IL (Intuitive Logic) circuits in the ECU, as the ECU learns your riding habits it reprograms itself. After approximately 1,000 miles it calculates if your competant enough to go to racer mode and electronically alters the mapping.

If your a advanced rider it begins programming the auto shift functions which are implented at 5,000 miles provided the gyroscope does not detect any evidence of lowside impacts. At 10,000 miles, and/or trackday data logging evidence, it implements the PRTC (pro racer traction control) module :thumbup


didn't anyone read the damn manual :confused:

:fact ;)

Errr... yes, it is BS. And I don't need to have an 07 to tell you that. I'm not knocking your bike, so don't get all offended, I'm just telling you that your ECU does not "learn" anything from the rider or bike, as some seem to think it does.

An engine is an analogue machine with many tiny variations. It changes with time due to wear and tear. That's why your engine's characteristics will change over time (break in). An ECU is a digital microcontroller. As such there is no and cannot be a "break in" period on it. Some are very fast and powerful, for sure, but I have never heard of any motorcycle's ECU "adapting", so I say BS. They just act on current info they're receiving from sensors on the bike. If you have some info about the 07 ECU in particular, post up, I'm all ears and always keen to learn. "Erm, my bike feels different" doesn't count, btw.

Help!!!!!!!!!!!

I live in the uk and have an 07 on order, all this throttle hesitation stuff is scaring me off the thing. If any one has any firm facts from a dealer please let me know before i take the plunge on a new bike. Throttle hesitation is crap on any bike "try the blade to see what i mean".

TBH I wouldn't worry. if there was a major issue Yamaha would hopefully jump on it ASAP, not in their interest not to. It's a dumb box of electronics fed info by sensors its not an artificial intelligence. If it was and you pussy the run in you would end up with a pussy of a liter bike.

Also all this ECU "learning" horsesh*t, if the ECU noticed the "throttle lag", if it existed, would compensate/ eradicate it next time round.

Some people are already pointing at the TPS because it was a known weakness in the previous model - It didn't cause the same symptoms (throttle lag) it was poor/non existent tickover or stalling at low revs.

The "FBW" throttle has already successfully spent 12 months on the R6.:thumbup

At the end of the day there are several '07 owners who are very happy.

One question to bear in mind are: Any of the new '07 owners new posters? (I have not looked). Many people join a relevant Forum to post problems the majority of happy owners don't.

Look forward to your new bike, and hopefully you will be a very happy owner.

I wish I could afford to do so.

YOu are Right. It would compensate for the problem. But Do Note this.A true Problem Is a 2 trip occurance.= This being 2 on off ignition Cycles with the same accuring problem .Depending on the manufacture spec. If it has to do a 20 mile drive or a 0-70 mph run for 5 mins.

And Being he was still on the ORIGINAL tank of gas , I HIGHLY Doubt if he has riddin it long enough for the computer to " LEARN " " UNDERSTAND " " FIGUREOUT" <-- you choose your wording .. the system to compensate for the Issue. This being the reason it never tripped a Check engine Code.

Hey.. But Noah Was right, It did rain for 40 days and 40 nights :sing:

I hear you but I doubt the 2007 ECU is that intelligent. If it had an AI it would surely incorporate traction control, or is throttle lag Yamaha's answer to traction control?

I am trying to dismiss this throttle stuff but i have to say that on my 04 in 2nd gear the rear tyre lights up a treat if you stick your weight over the front. If the 07 wont have any of that because of bullshit electronic traction control or power limiting "what ever you want to call it" then its not going to be such a mad fun bike!:thumbup
