Important Fitment Checks
- This kit is for electric-start engines using the matching chain-driven starter-clutch layout.
- Compare the 41T starter sprocket, starter chain, chain guides and clutch assembly with the photographs before ordering.
- Confirm the starter chain route, crankcase layout and mounting points match your engine.
- Do not order solely from engine capacity: Honda and Chinese horizontal engines were produced with several different starter systems.
- Kick-start-only engines will not accept this kit unless the engine already has the corresponding electric-start crankcase and starter-drive components.
