New Cast cylinder – Wrist Pin – Rings – Clips and Gaskets and 63mm Cast piston

Re-jetting of the carb is needed after installing this kit. We strongly suggest an aftermarket exhaust with any bore kit.

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