Problem! My '07 won't stay on!!!

Please read this whole post...I've read about the issues some people are having but this is something in addition to the issue of the bike cutting out when revving/blipping the throttle. I have an '07 and I never actually rode it in completely stock form, but I did start it before installing any mods and it died after running for about a minute. I never thought anything of it I guess. I had an injury which has kept me from riding so in the mean time I installed some mods with zero miles on the bike. Here's the only mods I have so far other than rearsets and some cosmetic stuff. 1. PCIII (with zero map) 2. Ignition module (with zero map) 3. Quick turn throttle 4. Graves Smog Plates Before today I only put 31 miles on the bike and it died every time I blipped the throttle while sitting still in neutral or in first as I approached a stop. I put 120 miles on the bike today and things seam a bit worse. Here's what's going on... The bike cut off almost every time I came to a stop today without even blipping the throttle. Doesn't matter whether I'm sitting still in neutral or in gear with the clutch pulled in. When I blip the throttle, the engine feels like it can't breath for a second and then lags for a second, then shuts off. I'm pissed about that, but the fact that it's just cutting off without me doing anything to the throttle is really frustrating. The only way I can keep the bike from shutting off while at a stop is by slowly opening the throttle and holding the rpms above 1500. And then starting off from a stop is the same way. I absolutely cannot rev the engine or it dies immediately. I don't care if the bike is new and I only have 150 miles on it, there is no way this is normal. I know some of you have had issues with your bikes cutting out as you come to a stop, but is it this bad for you? Any suggestions? I've lifted the tank to see if any hoses are pinched and nothing. I would think it definitely can't be the pcIII or ignition module since they are set on zero maps. And since the idle can't be manually adjusted I can't see how the quick turn throttle would be the cause of this? So that just leaves the Graves smog plates. Should I go as far as putting the bike back to stock even though it did die when I started it in stock form? This just doesn't feel like something that will go away as the miles increase. In fact it seems to be getting worse. I've never had issues like this with a new bike so any suggestions would really help me out. Thanks for reading.

You have no option but to put it back to stock and then if it still cuts out to get warrenty done. -btw mine cut out about 20 times 1 night (1,000km before 600 miles on the clock), it cut out on 2 furthur occasions a few days later, but since then hasn't cut out once 2,700km (knock wood). Mine cut out every time I pulled the clutch in, the rev needle would drop straight to zero and engine died. It was as if the idle didn't exist.

Yeah, return to 100% stock and try to diagonse from there, but for sure id suggest u do not go out riding ur bike far, or near traffic, if ur bike cuts out when u need to get out of a situation that will not be good. be safe. Curby

Mine cut out every time I pulled the clutch in, the rev needle would drop straight to zero and engine died. It was as if the idle didn't exist. That's exactly what's happening to me. Do you also have a knock then a hesitation if you rev the engine while either in neutral or with the clutch pulled in while in gear? Doing this also kills my engine. I guess I'll just keep trying to ride it and hope that it goes away. If not, I think you said it best. I'll have to put it back to stock and get some warranty work done. Oh, and just so I'm not missing anything...There is no way to adjust the idle on the '07, right? Man, I hope you're bike never cuts out again and hopefully this will just go away for me. It's not only annoying, but also embarrassing...Especially when it dies three times while sitting at a stop light in a busy intersection. I'm going to reset the throttle position for the power commander tomorrow and see if maybe that does anything.

Yep I hear the knock noise every now and then, when at low revs and accelerate a bit. I can't remember associating that knock noise with the engine cutting out though. I think I still hear it from time to time now :) When it happened to me (the 20 times in 1 night) i was out in the middle of the country going for a ride, was worried I might be stranded lol The 1st few times it cut out I was going down hill so I just clutched it, then on the way home i would just randomly pull the clutch in to see if it would die, 90% it did (needle dropped straight to zero) but i was going fast enough to just pull clutch in then drop it and clutch start it again. I know how you feel... It's a bit of a worry. But i'de put it back to stock and put some miles on it and see if it goes away. If not, straight to your dealer... And there is no idle screw to adjust.

I'm going to try resetting the throttle position on the PCIII and if that doesn't work than it's back to stock. Man those smog plates were such a pain to install too! Oh well...Thanks for the info. I think I feel better just knowing that it's not only my bike, but it definitely sucks for sure.

no probs... I just went to the shops and tested that knock noise on mine. I'll desribe mine and see if it's the same noise you hear. The noise sounds like a click or clunk sound. A lot like the clunk you hear when you change gear. If I hold the clutch in and blip(rev) it will clunk about 6 times then the noise goes away. It sounds like it is coming from the lower left hand side, maybe where the chain is on the front sprocket. I get the feeling that the clutch isn't quite right and it sounds like the gears or sprocket is clunking even though i have the clutch in. I have no mechanical experience so could be anything :D Is your knock sound like that? I also get a slight hesitation when I roll on the accelerator then the clunk noise then it accelerates normal. But the accelerator hesitation isn't as bad as it was when I 1st got the bike. It was quite notacble, now it hardly is.

Hey Dude Sorry To Hear Bout Your Idle Problem. My Idle Used To Fluctuate A Lot After I Installed My Exhaust. But I Was Using A Map For My Pciii That Was Meant For The Graves Slip On. Since Switching The Map To Something That Matches My Set Up I Noticed The Idle Raise A Little And Has Gotten Smoother...you Could Try That Before Stripping Everything Down......i Just Noticed That You Were Using A "zero" Map......

The best way to describe mine is by saying it's that same sound that you get if you stall out a bike or car. It's that knock that an engine makes right before it stalls out from not getting enough gas. It's not quite a clunk like when shifting to first from neutral, but I can definitely feel the knock.

I was actually thinking of trying out the map for the stock setup just to see if it would change things. The reason I'm just using a zero map is because I haven't installed the full system yet. And my bike is basically stock accept for the smog plates. I'm going to try that and reset the throttle position tomorrow. Hopefully one of the two works!!! Thanks for helping out! Much appreciated!:thumbup

I think I got rid of the stalling problem, but now there's a new problem that I need some help with. Today I unplugged the PCIII and Ignition module and plugged the stock connectors back together. I took the bike for a quick spin and it did not die once. If I rev the engine at idle it does not kill the engine or missfire like it felt before. This is where I need someone's help... The pcIII and Ignition module had zero maps, which shouldn't affect anything, right? So why does one or both of them make my stock bike run like crap? I have a feeling it's the ignition module since I've never had one on a bike and none of my bikes have had this problem. In addition I've never had a problem on any of my bikes while using a zero map, or any map for that matter. I guess I'll find out which one is giving me problems when I just re-install the pcIII without the ignition module tomorrow. I'm pretty sure that a zero map on the pcIII will not affect the bike whatsoever...Maybe a zero map on the ignition module does? In the mean time, if someone can give me their two cents I'd appreciate it. I'll do my test on the bike sometime tomorrow and hopefully figure out which one is causing this. Thanks.

It's not quite a clunk like when shifting to first from neutral, but I can definitely feel the knock. when u guys first get the bikes did u guys feel the bike is stuttering under 6000rpm? please let me know becuase this stutter is killing me it's not smooth and powerless. i dunno what to do this is really dissapointing. btw i only have 22 miles on the bike so far does it get better?

OMG... dude, I am so sorry to hear that. Get to stock trim and take that shit back to the dealer. WTF is going on with Yamaha this year.... Inbelievable!

Hi you should not put a zero map on you bike as this is all zero put a stock map on look at the pic

Hi you should not put a zero map on you bike as this is all zero put a stock map on look at the pic I appreciate your input, but that has nothing to do with why my bike stalls out, misfires and runs like crap...It's the ignition module. It doesn't matter what pcIII map I use ('cause I've tried a bunch of them), as long as the ignition module is installed the bike runs like a piece. It's going back to dynojet monday.
