Installation notes:
Re-jetting of the carb is needed after installing this kit. We strongly suggest an aftermarket exhaust with any bore kit. Case boring is required.

We also have performance CDI's to increase rpm limiter, bigger carburetors, high compression piston kit, racing exhaust, custom crankshaft, etc.
