i have a 2001 warrior 350 and whenever i hit the throttle fast it will bog down backfire and then run fine again i already gave it a full tune up and cleaned out the carb... any help?

 

mine does the same thing. it's the accelerator pump. i replaced mine and it still does it. but it's fine if i ease into it.

 

well that dosnt help much i want to stop it from doing that completely

 

i'm not really sure what else it could be other than your accelerator pump. but then again it could be a jetting problem or something else. i read on another forum on thumper talk and one guy had the same problem and someone told him it may be a jetting problem.

anyone else have any suggestions on this?

 

My big bear does that now i have a snorkel, ive been told it was a jetting prob so i got a jet kit coming in. Will get back to you if no one else does,
