Got a slighty missing, staggering, or stumbling Nytro?

[MotoPsycho]

After an entire season of riding, multiple trips to the dealer, and several hundred dollars... I found my problem.

My sled would hesitate, sometimes with a slight pop (afterfire), upon a quick "stab" of the throttle. It didn't matter if it was from a dead stop, riding at constant speed, or slowly accelerating, it was after the "stab".

Although I prefer to do my own wrenching, I took it to the dealer on more than 1 occasion for this problem. (After all, that is what the great warranty!!! )

The first few times, they dismissed it entirely. The 3rd time, I insisted it was a ridability issue, and I wanted it resolved. I metioned that they may want to check the throttle body sync as well, as this may be the root of the problem. This particular trip was also my 500 mile check-up. Much to my dismay, I went to pick up my sled, and had a $420 bill as well. It was okay though.... my sled was no different than when I dropped it off - miss, and pop included.

Anyway, long story short, it's all about the TORS system. Throttle cable slack is the key - you don't want ANY SLACK in the cable!!! (or at least "minimal" slack) If there is excessive throttle cable slack, the cam device in your flipper will activate the TORS for a split second upon a quick stab on the throttle, which drops the engine to idle for a split second. This makes it seem as though you have a miss.

Just my .02 - hope it helps someone else out

Warranty

In defence of the warranty thing, I had my daughters '07 Phazer in for a reverse issue last year and was given a new belt under warranty that resolved the problem. Also the starter was acting up and a new one installed as per Yamaha Instructions. All under warranty. Maybe there are other issues here? I'm nothing special where i deal so I don't think it's anything anyone else would not receive. Just my $.02. that's $.016cd $

my tors started to act up and it would sometimes just about put you over the handle bars when it kicked in.....the answer was disconnect it and teather up!

Yamaha is great about warranties!!!

In most cases as above the dealer is the one to blame not Yamaha. Some dealers do not want to work for the amount that the manufacter alots on warranty claims. They would rather send you out the door with a $420 bill and tell you that it is not a warranty issue.

Very true!! The dealers don't get "paid" enough for it most times, in comparison to retail maintenance work. It's better than nothing tho. I do my own wrenching, UNLESS it's a warranty issue....even then I would rather get the parts free and do the work myself, I just don't trust anyone to work on my stuff that much.

The dealer normally decides what is warrantied and what isn't. Yamaha will almost always side with what the dealer recommends or feels is the issue. Maybe, you should look at a buying from a different Yamaha dealer.

My original post was more about the problem I found and how to rectify it.

My dealer treats me fairly well for the most part, but it never fails that we all have a bad day now and then. They did just what I had asked them to do, I just felt as a ridability issue, it would have been covered under warranty.

My Nytro has that same miss\pop thing going on as well. Alot of guys on here were saying that the throttle bodies (I think) were out of sync, so I took it to my dealer and the covered it under warr. It was a little better, but I guess I'll check the slack in the cable. Thanks!

That was another thing... The VERY LAST STEP of the throttle body sync (as per the service manual), is to adjust throttle cable tension. After I found my problem, I quized my dealer about whether or not they adjusted it. The tech told me...

no.

It may help ya out Zsnow
