recently i've been having some problems with the acceleration on my kfx400...no idea what it is...maybe the fuel...i can start it just fine, and you can even move it around at low speeds in first gear...but once you try to give it some good gas or take off it just turns off...any advice?? thanks guys

 

Hmmm youve got a real head scratcher there. Did you try cleaning out your carb? Not sure what type of carb is in those bike but it could be something to do with a diaphgam or the acellerator pump.

 

clean the carb, did you recently just do any jetting mods or did the bike sit for over a month??

clean your air filter too. maybe drain all the gas out and put new stuff

 

yeah i jetted it about a month ago or so, it worked fine..and all of a sudden it's doing this..how would i go about cleaning the carb...i yank it out and then what? i'll try cleanin the filter too thanks
