Cometic Top — Yamaha YZ85 (2019), End Gasket Kit

Pulling the head for a rebuild and you need every gasket and seal in one go. Cometic's top-end kit includes the head gasket, base gasket, valve-cover gasket, exhaust gasket, intake-manifold gasket, and the small o-rings and seals that the OEM kit usually leaves out. Materials run to spec for your engine — MLS for stock-bore heads, copper or RC composite where the build calls for it.
