Top End Gasket Kit - 68 mm - Yamaha

The COMETIC C7142 Top End Gasket Kit is designed specifically for Yamaha models with a 68mm bore, providing a comprehensive solution for top end rebuilds and performance upgrades. This kit includes a high-quality MLS head gasket, base gasket, and cylinder O-rings, as well as additional seals required for efficient removal and installation. Engineered for high-output 4-stroke engines, whether naturally aspirated or boosted, these gaskets feature a multi-layered steel (MLS) design with embossed outer layers coated with Viton rubber, ensuring durability and superior sealing under extreme conditions. The design promotes even torque distribution across the gasket surface, reducing bore distortion and enhancing piston ring sealing for increased power and reliability. The EST (Extreme Sealing Technology) gasket material incorporates embossed stainless steel components covered with a proprietary rubber, which facilitates heat dissipation from the combustion chamber and prevents hot spots that could lead to gasket failure. These gaskets are built to withstand high-cylinder pressures and high horsepower applications, making them ideal for performance enthusiasts seeking longevity and optimal engine performance. Suitable for Yamaha engines with a 68mm bore, the kit ensures perfect fitment and restoration of sealing integrity.
