Frequently Asked Questions

Will this fit my Harley Sportster?

No — this gasket is for big-twin engines only. Sportster models require a different primary gasket.

One OEM-specification primary gasket per package.

Do I need to replace the gasket during routine maintenance?

If you have the primary cover off for service, Cometic recommends replacing the gasket to prevent primary fluid leaks.
