Converts 3-speed semi-auto clutch to a 3-speed manual clutch. 67/18 Primary gears with a two-plate clutch. Can properly handle an 88cc Bore/Race Head combination without clutch slippage and loss of power. Unlike some other similar kits on the market, this kit includes the correct length shift shaft for the newer Honda engines so no additional modifications are necessary. Comes with everything pictured including an allen head bolt kit for the engine cases. Does not include perch and lever due to many application options. Very nice option to use with the 88cc bore kits for even more fun and performance.
