ok i just got a yzf250 dirtbike yamaha it wont idle and whenever i let off the gas it just backfires like crazy but when givin her gas she takes off like crazy it has a quickshot device on the bottom of the carb and also has a high compression piston in. its an o4 i was wondering if the pipe is out of packing or something causing it to do so but im not sure.
