2001 Yamaha Big Bear - Studdering

[Cliff]

Hello I need some help I have a 2001 big bear 350 2-wheel drive that runs good while in neutral but when you put it in gear and try to ride it. It sounds like it's constantly hitting a rev limiter any one ever heard of one doing any thing like this ?

probably a dirty carb ... and/or float level needs adjusting

I have a 98 350 with the same problem it falls on its face just past about mid range. I have cleaned the entire fuel system and even replaced the black exciter box i am stuck at this point not sure if this machine has a rev. Control.hope someone has seen a cure for this.

Rejet the carb i bought a carb new/refirbished from zoom and it came with too small a pilot jet it had like a 25 in it i had a 30 just laying around got better but still not right i ordered the stick size a 42.5 from pjmotorsports huge difference runs like a scalded dog but I have other issues now like stop sparking once hot replaced all coils beside the primary coil only because I can't figure out how to get my stator off and now it only Sparks Once when you first hit the starter anyway hope that helped
