ok so a while back i bought an 87 cbr hurrican to stunt, i got it really cheap and it is only running on either 2 or 3 cyls. and if you are sitting on the bike the carbs on the right hand side are leaking gas,i cleaned floats and still ran like crap,and also still leaks.not really sure about carbs much,could it be part of the problem?...so i checked for spark and it sparks..checked plugs they looked old so i replaced em.. and i was just woundering some general things to check and look for as i am pretty new to working on bikes. any help would be amazing and thanks alot..i have no idea what i should be looking for
