I have not heard of a "known" TPS issue, on the 07, but the stalling, has been linked in part to the clutch on the North American (US and Canada models). Having a creafully adjusted clutch seems to alleviate some of our stalling issues. Remember the bike that you have on that side of the pond is actually different than what we have in the US, hence the reason you did not need to have your ECU replaced for the 5500 RPM, 2nd gear, throttle lag problem. Perhaps someone else from the UK will chime in :dunno

 

i bought my 07 back in july and it has stalled three times. not really a big deal to me but i would like it to stop. can you explain what you mean by a carefully adjusted clutch? thanks

 

from the uk here,

had the same problem on my 07, booked it in and got it replaced through the warranty. Was ok for a month or so but its happened again so will take it back till its sorted for good.

Dangerous though i tell you that, purely because it so random, mine stalled as i went for an overtake on a country road. brown trouser moment!!!

 

I must be honest i have not heard about any issues effecting our UK 07 bikes, but given there are 2 of you with this same issue maybe there is.

I am going to throw a wild card into this and tell you about a problem i had with my 06 bike. I was mid overtake and my bike "stalled" on me. Luckily it was on a long striaght and nothing was coming the other way, the car i was trying to pass went ahead and i pulled over thinking WTF just happened.

It turned out that when i put the ignition on i had not turned the key all the way and clicked it into position. The key moved with vibration and effectivley shut the bike down. It didn't make the issue any less scary, but at least i was relevied i didn't have a dangerous fault on the bike. So what i am saying is be sure to tunr the key fully and it locks into position. I made the mistake by turning the key with gloved hands and not concentrating. A long shot i agree maybe but still a possibility.

There are several threads about this problem.

I've had two -07s and they both had this thing that the engine randomly cut out during down shifting.
On the first one they changed both the TPSs, no difference.

Recently Yamaha went out with a "fix" to the problem, so what they done on my second -07 is they turned out the syncronisation screws a bit on all four throttle bodys and they put a thin chime between throttle body and TPS.

Is the problem gone? Well, i have only run the bike a couple of times for less than a hour a time (it's kind of winter here in Sweden) but it hasn't stalled, so only time can tell if it works.

Hopefully it worked out for you Ozzian...

 

Thanks XITNU

Yesterday i got 1.5 hour of nice riding in 41degF on snow free roads
(thanks global warming?)...

However, no stalling so far, the idle still dropp some from time to time but never so much that it causes the engine to stall.

I hope Yamaha have gone out with this world wide by now so i wish some more people (in warmer countries) with this problem could get their bikes "fixed", it would for sure shorten the time for all of us to know if it really works.

I'm frequently at the shop because of the idle drop but they want me to drive some more, their main concern is getting rid of the stalling, i myself link the problems to more things such as: High fuel consumption, randomly poor lower midrange, (which seem better now, on the other hand, last time i rode properly was in october), and sometimes rough idle.

So please, if you have this problem with stalling, talk to your dealer to get the fix done and get back here with the results :thumbup

Cheers Ozzian, just got a call from the dealer saying the bike will be ready for collection tomorrow. you described the fix with the syncro screws a fair bit better than my attempt. will try and get a few hours in this weekend but its still not that much warmer here in the UK than in Sweden.

Congrats matelot, hope you feel any improvement.... And just in this moment the snow began falling out side the window, winter is back:crash-- Why now???

I don't know if Yamaha think it's allright for me to tell this...? But what the hell..

They turned out the syncronisation screws half a turn each (CCV).
Put a 0.35mm shime between the throttle body and TPS.
The funny thing is it was a round shime which means that the "wings" where the two screws is fitted will bend some so the shop was told not to tight the screws too much.

 

I have the stalling issue. It seems as though it occurs after I have ridden for a while, or if I have hit the rev limiter. Starting to really piss me off.

 

i live at indonesia, a very hot country....
my 08 will stall after some minutes ride......
interest on turn out the air screw half.....please tell me which one the screw and how i do it....

thanks

 

I was a little bit worried about this, the best is if you tell your dealer you know about Yamahas "fix to the problem", then all the responsibilitys are theirs.

I don't know if turning the screws out could cause the engine to run lean and if they had to compensate for that in some way?

Edit: Okey, just saw you got all the answers in the stalling issue thread ;-)

 

The only probs i had with my 07 were the ecu and the unlucky rock piercing my radiator costing me 500 bucks

 

For future reference, you can get your radiator repaired for much less than that.

 

Just had my first spirited ride on the 1 since the work was carried out and theres been no recurrance at all of the cutting out
the bike does idle a fair bit higher than it did, a little less than 2k revs, which was unnerving as its not really what i'm used to but hey ho.

can someone tell me what the bike idles at normally when warmd through?

 

The idle shouldn't get that high, then they opened the sync screws far to much (or something else is wrong), normaly the ECU try to keep the idle at 1200 rpm, what's the rpm during warmup?

 

I got about 800 miles on my bike, hasnt stalled once.....knock on wood!!

Hi all, Iam new to the forum and have been reading this thread with intrest.
I have recently purchased a new 08 R1 here in the north east of England. The very first time i took the bike out i had the problem of the bike stalling out on down shifts. The bike ran fine for an hour or so then it started. I thought it was just because the bike was new and was breaking in in as i previously had a 06 r6 and this was a bit eratic when new till i got a few hundred miles on it.
The problem is the R1 was doing this regular about 4 or 5 times in 100 miles especially when down changing or rolling off the throttle quite scary when entering corners as the back end was stepping out of line. Also there was the odd occasion on acceleration where the bike would die then you would give it full throttle and it would burst into life and try to take off like a missile.
After this i decided to go to the dealer and see if there were any issues they new about and the only thing they commented on was that they had to adjust the tick over on a few yamahas this year. They also said the bike may settle when it had a few more miles on it and recommended starting the bike without any throttle at all and just let the bike tick over for 15-20 mins with out touching the throttle which is the really important part.
He also said if there was still a problem i should book it in and they would take a look.
I thought it was worth a try so when i got back home i decided to give it a go as it would do no harm and iam surprised to say the next time i took it out the problem had disappeared. I could not believe it.
I would also like to add that i disconnected the battery for a few hours before this procedure as i wanted to fit a battery tender lead and thought it would do the bike no
harm.
So i now have 430 miles on her now and i must say i have only had one slight moment since the first time and nothing since, i hope this has sorted it.

This is a interesting thing.
i've had my thoughts on some kind of adaption problem and this could be something like that.

Since the increase of the bypassair through the sync screws the bike hasn't stalled (yet) but it still have that occasional drop of idle.

I will try this thing to.

 

good to hear! glad your going to get the chance to enjoy it. Must admit theres nothing quite as buttock clenching as when you lose power mid corner. where abouts in the north east are you and which dealer have you been using??

 

Iam from the town of Barnard Castle and the dealer i bought the bike from is M&S of Newcastle.

 

boy, after reading about the 2nd gear lag issue, now this stall, do i really want an 08! I want an R1 but was going to wait till later this year to get one hoping that later in the year builds of the 08 would sort out all the 07 issues. I never buy first gen redesigns which the 09 will be.

 

how to adjust tps?

Hi- I'm new here. Can I get an explanation of the TPS setting procedure please? The "Air Screw" - is this related? Thanks!
Dan

 

thanks, but that doesnt help much! anybody care to explain the stalling fix in detail? thanks in advance.

 

That's why I said "For future reference.":secret:

 

I think the fix was posted on page 10 of this thread

thank you- sounds very easy!

 

My R1 just started stalling when coming to a stop. I'm not sure if it is TPS issue, funny thing is it starts running fine right after refueling.
