We recommend a flat-slide carburetor kit, hi-flow head with 1mm over valves and an open exhaust system with these rebuilds to optimize the performance that you have paid for. We offer both as well as a 2 into 1 and 2 into stainless steel or mild steel exhaust systems.

Engine building service is available—we charge a 500.00 flat rate plus shipping costs (shipping costs depend on the distance and service you use) if you ship us your engine to rebuild it to the specifications you have ordered.
