banshee running issues after rebuild

[FMF shee 98]

ok i just rebuilt my banshee .40 over with vitos pistons and the right pipe is backfireing bad and the bike will rev up and down. and i switched the carbs and it was running pretty got both sides were fireing. i need advise ASAP do the carbs need rebuilt? jetted? and i already cleaned them

well, if they are stock carbs, the first thing i would check is the choke tube. it's a peice of vaccuume line that connects from the back of the choke knob to the other carb. that will cause a major air leak on the left carb. if that's fine. look all over for air leaks. do a leak-down test, and clean the carbs real good, including both jets and passageways.

there is no tube going across

ok, do you have only 1 choke knob on one carb only, and it puls strait out of the side, not up? if so, you need that hose going across.
