RUFFSTUFF,

My bike does this, but not consistently. Probably every 300-500 miles, the idle will drop to around 400 or 500 rpms and the bike will cut out. If I shut it off and restart it a few minutes later, the problem is gone completely and it idles like new again. Are these the same symptoms you had? or did your bike cut out all of the time?

 

my bike drops down and idle low-however not now since they added more fuel---it is not lean anymore---it used to just drop down to 500 and sometimes die, but i used to turn it off and restart it because I knew what was going to happen next.

yes-i have to turn it off and restart mine also and it runs for a while or the day but for certian it will do it the next day.

For the most part-mine shuts off when i let go off the throttle while comming to a stop with clutch pulled in.

I AM LOOKING FOR PEOPLE TO ADD THEIR FIXES TO MY POST.
I WANT TO KNOW IF IT WAS REPORTED TO YAMAHA, AND WHAT PARTS DID THEY SEND TO FIX IT. IF SOMEONE HAS A NAME OF THE PERSON AT YAMAHA (US OR OTHER) THAT THEY SPOKE TO, PLEASE PM ME WITH IT SO CANADA CAN CALL THAT PERSON.

THANKS,
D.

We had same problems. 'No concrete fix....has not been a problem for the last months

 

I am adding to this thread from my old thread.

I have some serious problems with the 04 today. On the way to work at about 70mph my bike starts lurching. Feels like a fuel problem, but its cutting out. Then when you get on it no problem at all. It still runs like a beast, but then a came to my first stop after that and idle drops to half and then it dies. Did this for the next 25 miles or so. I adjusted the idle and it was ok for about half that and now it doing it even at 15mph. Just lurching bad.

I am thinking it could be bad gas or something. I am going to change gas stations after I run it out and see if this is the issue.

Anyone had this problem yet? My mods are listed in my sig which I did like a 1000 miles ago and I have no errors on the dash, so I don't think they could be cuasing this.

 

This happened to me around 5000 miles and I thought it might just have been bad gas or that flat spot with the stock exhaust and exup valve. I went with a full Graves a couple weeks ago and today the problem came back and got even worse. It cut idle in half and then died. I finally pulled over and cranked the idle up and it seemed to go away. That was the first tiem i turned the key off as well. Before when it died I just restarted it.

I went another 15 miles and then it started to cut out at like 15mph and then died again. I still have 50 miles to get it home from work

I checked with my dealer and they have had no calls on this yet.

 

So I went to the dealer to get this checked out and they had to call Yamaha direct to see if they knew anything. Turns out they do knoww about this issue, but they are being very quiet as they have no idea what is causing it. They wanted to drill holes in my header and attach some tool )the dealer would have to order because they didn't even have it) and read what the engine is burning. I of course said He!! NO! I have a full Graves on mine but of course they think my bike is stock

So this is a known issue with no resolve as of yet. Yamaha thinks it's the TPS sensor or the throttle bodies. That would sound right according to what I have been reading on several other threads on this subject. The TPS is $120 and the bike has 2, so it's not something they will just swap out to see if thats it. Even under warranty. So at this point I am monitoring the issue and waiting for someone or Yamaha to figure out.

This is very dangerous as you can stall in turns and lights, pretty much anywhere. I am wondering if the guy in another thread that had a crash in a corner he was going slow might have had a stall and then severe engine braking

So stay tuned and be careful until they address this issue.

I will try to get this thread to be a sticky....Hey moderator, make this a sticky...its a safety issue!

 

Okay, my problem came back tonight same as before, hesitation, then stalling, with a rough idle.. In most cases, if I turned the bike off with the key, waited a few moments and then started it back up, it would idle normally. But then the hesitation would come back at some point....


This sucks.

My 02 has almost 35,000 miles, and other than shitty footpegs, not a single issue!

 

Well I have a case ID open with Yamaha, so hopefully they figure it out.

I was having so much fun with the bike until this crap started to happen. From what i hear it just gets worse and more frequent

 

Be interested what becomes of this .Bike just started doing this,just over 8000kms

 

Well, I'm going back to tell the dealer today... we thought it was fixed when the coils were changed, but oh well!

 

From what Yamaha is telling me I think it's the TPS sensors, but swapping them out won't help if they are not working because of a design problem. This seems to happen after some mileage, so others will most likely start to have these issues as well.

Mine rides fine now, but it will do it again. It totally suucks when it hapens.

Everyone should be safe and when going 2 up make sure they hold on the jerking can get really bad at times. i was one handing it on an open road and almost flew off when it cut out

Hope they come up with a fix fast! I will post any news I get on it. Please do the same if you get a fix or hear something.

 

same here mine first did it at around 8-9k miles. I too thought it was the gas. I now have 14k on her now hasn't surged since then, but now that i'm posting this it'll probably come back.

 

Mine started around 6-7k. I now have over 10k.

Remind me if I haven't said that this sucks.

 

I keep telling everybody it is the tps. My bike did the exact same thing that everyone is explaining. My bike started acting up early at around 2000 miles I think. Anyways they replaced the tps and reprogrammed the bike and it has been running perfect ever sense. I think that it was bad out of the box because when they fixed it, the bike ran ten times better. I got my bike fixed from champion yamaha it mt pleasant south carolina. If anyone has any specific questions the number their is (843) 856-8656.

 

idle cut out

i have the same proble ,for a couple of days now.(7600 kms)
it seems that nobody has the answer not even yamaha. please if you find anything important let me know.

 

same problem here. I have 3,800 miles on mine. Just started doing it right after 3,500 and after I had the engine all torn apart. I thought it was something I did wrong when I was putting it all back together.

I now run the idle up at around 1,600 / 1,700 rpms. Thats kinda high for daily riding. But it gets rid of the problem for me (so far). I tried to go back to a lower idle, cut off again.

 

PLEASE ONLY POST IF YOU HAVE THIS PROBLEM OR HAD YOUR PROBLEM FIXED.

All,
I started this post and provided what I was looking for. Please follow the request. I do not want just try this or try that.
I want to know:
1. who has the problem, when did it start how many miles or km
2. has it been fixed and how and when, where
3. post your info in your original post-do not start new posts for each update as it makes it harder to track the issue.

I have pm those indivuals to remove their posts and to edit multpile posts into 1 post. If the cooperation is not there then I will ask the mod. to remove and edit this thread.

Sorry, not trying to be a control freak, but this issue is DANGEROUS-trust me. I keep asking all that has this issue to not take a passenger and the problem does get worse. Call Yamaha and tell them-try and get some report# for proof.

Thanks, and hopefully noone flames me:boom

 

I got this problem, The bike dosen't cut out but feels like its going to or it feels like it has no gas being fed to the enging when i'm off the throttle and decelerating in high rpm's. 2500 miles started 1,500 miles on it. I have micron slip-on with out a pc3, So i was just thinking it was me not having the pc3.

 

PLEASE STOP POSTING opinions HERE---WE ARE TRYING TO GET A VERY SERIOUS PROBLEM TRACKED AND SOLVE HERE.
I AM SPENDING TIME TRYING TO TRACK EVERYONE WITH THIS PROBLEM FOR WARRANTY AND ANY LEGAL ISSUES THAT MAY ARISE.
post if u have this problem or if it was fixed.
THANKS FOR YOUR COOPERATION-

 

OK, it cut out in a left turn why I was yeilding and I almost got taken out by a 4x4 raised Ford

Yamaha better get a handle on this before someone gets hurt. I can tell you right now I will sue if I get hurt until I own the company! Rossi will be riding for me!

Turning the key off seems to help get rid of it for a bit, but it comes right back. Been more frequent lately too. I need this bike for work dam'it:fact

 

My 04 cut out suddenly on a right hand downhill turn at WSIR, T4b. No previous hint of any problems, and no warnings at all. No time to pull in the clutch or react in anyway, except to try to not tumble as I went asphault surfing. The bike is a total loss. :crash

 

mine did this one time, I did an endo and the bike started sputtering and cut off. The shiftlight I believe started blinking the error code but I was sitting in the middle of the road and couldnt get the bike to crank I truned off the key and back on then cranked fine...no problems since thank goodness.

 

mine is 7400 miles oil changed properly and all service done according to yamaha.

 

Mine is going to the dealer today. I spoke with Yamaha direct and they do not think it is the TPS sensor. They said that would happen all the time then. They are willing to send an exhuast to my dealer to have it drilled and hooked up to a machine for reading. It's not runnning lean either. I am on a powercommender with a Graves system

Eyespy, Yamaha knows about this and has done nothing. Time for you to get a lawyer and get another bike for free. That totally sucks. I am supposed to be racing this next month in the Toyota 200 too:rant

I will post when I get feedback from the dealer.

I am also going to call Graves and see if they know anything.

 

Well I have been thinking and This mostly happens when my gas light is on. Always trying to keep the least amount of gas in the bike while on the track. I do most of my laps with the gas light on. And this Is when I Notice it the most.
