I have a 2003 Raptor 660. After a wreck last weekend, whenever I start my quad it runs very poorly. It idles ok, but when given some throttle, it sputters, backfires and it won't rev. It will drive, but at like 2 mph and it sputters and backfires the whole time. We noticed, the carb was not fully inside the joint boot to the motor and was possibly sucking air. I found the boot was ripped and replaced them. Still no luck. It's still doing the same thing and I can't figure it out. any advice?

 

probally like my wolverne 450,, sounds ;like a stupid saftey switch is activating the rev limiter... parking switch or nuetral switch

 

So where is this switch and how did you fix it?

 

make sure the rev limiter is tight it is on the left side of the handle bar make sure it is tight that has happend to me once

 

Thanks a lot for the help. After I had wrecked and replaced the clutch lever I never really tightened the part of the perch with that switch in it. I was focusing more on the carb. So after over 200 dollars in parts trying to fix a carb/ air flow problem, it was just a stupid switch. I feel like an idiot. I read more about this problem in other threads and other forums.

Thanks a bunch guys. shes running beautiful again. So looks like I will be racing next weekend after all.
