Cometic Top End Gasket Kit 77mm Bore Fits Yamaha

The Cometic Top End Gasket Kit is a high-performance solution designed for efficient and reliable engine sealing. Specifically engineered for today's high-output engines, it includes all the necessary components to rebuild the top end of your engine, such as head, base, intake, power valve, cam chain tensioner, and other essential gaskets, seals, and O-rings. Featuring Extreme Sealing Technology (EST), the kit utilizes embossed stainless steel head, base, and rocker gaskets coated with a proprietary rubber material for superior durability. The multi-layered steel (MLS) head gaskets are designed to promote even torque distribution, reducing bore distortion and enhancing piston ring seal for improved performance. The head gasket material effectively dissipates heat from the combustion ring, preventing hot spots and gasket failures. Cometic gaskets are built to withstand the demands of high-horsepower, high-cylinder-pressure engines, making them suitable for a variety of applications, including Powersports, street bikes, snowmobiles, and V-twin engines. Trusted by top engine builders since 1989, these gaskets are crafted from premium materials to ensure maximum power, performance, and reliability. This comprehensive kit offers a competitive, high-quality option for rebuilding your engine top end, ensuring optimal sealing and performance.
