this sounds to me like all of that is new. but now your saying that the jet kit was in by previous owner. did you put in a new air filter and then have this trouble? if so, its definitely wrong jet sizes.i have a new filter desnorkled jet kit and full exhaust. what gives?
i meant that the problem didnt arise until a couple rides after the new filter was put in. it revs fine in neutral. i think the best thing is to just take it to a mechanic and have them clean and sync the carbs.what!?!? so, it didnt work when you put in a new air filter, but it rode just fine.......i give up, good luck to you.
