I am having trouble with my carb. abviously. I have exhaust K&N on it and I resently put a 6inch vent in the airbox lid. but now when u crack the throttle wide open it sputters and bogs. I figure its the main jet thats the problem but I do not know if it is adjustable or if you juss have to replace it. if its best to just replace it then I will do that. If its not the main jet then what is it. Can someone please help me out.
THANX
