Top End Gasket Kit - 97 mm - Yamaha

The COMETIC Top End Gasket Kit for Yamaha engines with a 97 mm bore size offers a comprehensive solution for top end rebuilds and repairs. This kit includes precision-engineered base and head gaskets, along with cylinder O-rings and other critical seals required for efficient removal and installation of the top end components.
