Just bought a 91 CBR 600 F2. Its my first bike, and it has a little miss around 1500 rpms. Anyone had this problem before? It has an after market yoshimira pipe on it and a friend of mine said maybe that would be the problem. Any input would be nice.

 

has it been jetted? If so it may have been jetted and then the aftermarket pipe put on after the jetting. That may account for the missing. Not sure, just a thought though

It may be the cable too...im not sure, like i said im pretty new to street bikes.

 

Im not sure if it has been jetted either...
