[01boneless]

ok guys sorry for all the new threads but idk anything about 450s so any way the one im plannin on trading has a nmotion full exaust (loud!! 120dbs) and a uni and is rejetted (idk what sizes) but for the most part sounds real good no poping!!!!! but i did notice on reving decel it shot a small flame once or twice now from what i know it indicates lean buti was told since the pipes are so open and loud its normal like i say no poping!!!?

it could just be incomplete combustion from inferior fuel quality

Yeah i wouldnt worry about a small flame. If you get it put a decent exhaust system on it and pull the plug to see how its jetted. If the plug is white then just do some jetting
