Important Fitment Checks
- Compare both caps with the parts currently fitted before ordering.
- Confirm the small timing / A.C. generator inspection opening and the larger crank-access opening match the supplied cap diameters and threads.
- Check the left crankcase / magneto cover style, as replacement engines and aftermarket covers can use different thread sizes.
- Fit suitable O-rings and do not overtighten the caps into the aluminium engine cover.
- Model information is a guide; production year, market and previous engine swaps can change the cover specification.
