one part number. All parts are available separately for custom builds.
• Complete kit includes: Shaped, domed cylinder head, state of the art cylinder with special porting, lighter flat top piston
assembly (all of which are designed for higher compression and improved combustion efficiency), forged crankshaft
assembly with larger 12mm wrist pin, top end gasket set, 19mm Dell’Orto carburetor, carbon reed valve petals, and Athena
racing exhaust system, throttle cable sold separately, replacement of clutch rollers and springs may be needed for proper
tuning
• Cylinder kits include cylinder, head, piston assembly, reeds, and gaskets
• Piston kits include piston, rings, wrist pin, and circlips
• Carburetors have a manual choke assembly and include a selection of main jets
• Hyper Race crankshafts have a lighter connecting rod, full crank rounds, and special needle bearings, but will not work
with OEM type stock or standard Athena big bore pistons due to the larger 12mm wrist pin size.
