About Cometic
Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.
Don't let a seeping inspection cover spoil the look of your Evo Big Twin. This Cometic inspection/derby cover gasket is engineered as a direct replacement, providing a reliable, oil-resistant seal. Keep your primary dry and your ride looking clean with a fresh gasket.

Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather

Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
