This kit is designed and intended to be 100 % race legal for the RMSHA Improved Stock and Mod 900 classes, and it will make a stellar back country engine package too. Kit includes CNC Boring and Porting, Nikasil Plating, Billet Exhaust Valves, Piston Kits, Stealth Head Kit with Billet Domes, and a Base Gasket.

Kit requires premium 91+ octane fuel.

NOTE: Your stock cylinders and head must be sent in for exchange, or the parts are available for outright purchase if you wish to keep your stock parts- select your choice from the core options menu.

Additional parts are required for proper performance such as our Single Pipe Kit, Lightweight Muffler, Hypershift Clutch Kit, Dynojet Power Commander V Fuel Controller, etc. Parts such as a Timing Key, High Flow Intake, Reeds, Throttle Body Boring and more will be tested as well- exact recommended components and specs are pending dyno and field testing.
