Description

Bolt on power – Huge 40mm intake cylinder with a large round exhaust port and a deep trenched boost port. Included is a highly polished Oz style 4 petal carbon reed system with 19mm & 21mm intake, polished fin work and decked surfaces. Transfer ports have been modified and the exhaust timing lifted. Piston is a modified type A and has a polished dome.

This cylinder / piston is setup for a 40mm PK80 style engine and requires 2 base gaskets or you may use 1 base gasket so long as you check your squish band. Will also work on the 39.5mm A80 engines with the same instructions for the base gaskets. If you have a 38mm rod get with me for a type B piston and some decking to up the compression on your setup.

The step up to stage two will require and expansion chamber exhaust system that is unrestricted. There are several on the market and we can get you some leads. The carburetor will need to be tuned and hopefully you have something in the 16 to 21 range, we have some suggestions on that as well.

Comes with nuts, bolts and gaskets for a quick and easy install.
