Compatibility

Compare the original assembly's overall length, splines, gear profile and return-spring arrangement before ordering. This part serves the mechanical kickstart drive, not the electric starter. Kickstart operation still depends on the engine's ignition and fuel systems.

For installation, follow the service manual's lubrication and spring-preload instructions, keep grease away from the belt and pulley faces, and check that the lever returns freely before use.
