Basic kit for improving the performance of GX160, 200s, and Chinese 6.5 Engines. Simple to install, you can expect significant performance increases.

For those looking to get the maximum performance without opening up the case, we offer our stage 2 kit. Where possible, we only use genuine Honda components to improve reliability and power. Same as our stage 1 kit but with the addition of a bored carb and to produce a solid 10+ hp on GX200s.

Now you are getting serious. A set-up from Stage 2 kit, we add a cam and a choice of carburetors. A billet rod and all need gaskets are also included. HP will range between 11 and 14 depending on cam/carb selected.

Our Stage 4+ kits allows you to customize a kit for your application. The 4+ kit starts with package similar to that of the stage 3 kit but adds a Ported and Milled Head, stainless valves, billet rockers, and a serious cam package. Options include everything from roller rockers to stroker kits. This kit will allow you to build a motor in excess of 20+ hp.
