Cometic Top End EST Gasket Kit for Yamaha 98mm C3068-EST

Top End EST Gasket Kit - 98 mm - Yamaha

The Cometic C3068-EST Top End Gasket Kit is designed for high-performance Yamaha engines, providing a reliable solution for top end rebuilds on 4-stroke models. This kit includes a base gasket, a head gasket, and cylinder O-rings, along with other essential seals and O-rings required for a comprehensive top end overhaul. The MLS (multi-layer steel) head gaskets promote even torque distribution across the sealing surface, reducing bore distortion and enhancing piston ring sealing for increased power output. Built to withstand the demands of high-horsepower and high-cylinder-pressure engines, these gaskets are ideal for naturally aspirated or boosted Yamaha machines.

The EST (Extreme Sealing Technology) gasket kit features embossed stainless steel head, base, and rocker gaskets coated with a proprietary rubber material. This construction allows heat to be efficiently drawn away from the combustion chamber, preventing hot spots and minimizing the risk of gasket failure. The multi-layered steel design, with embossed outer layers coated with Viton rubber, ensures durability and superior sealing performance. These gaskets are manufactured in the USA to meet the highest quality standards.

Compatible with Yamaha engines requiring a 98 mm gasket diameter, the Cometic C3068-EST kit is suitable for various Yamaha models such as YZ, WR, and other 4-stroke applications. It is an essential upgrade for enthusiasts seeking increased reliability and performance during engine rebuilds or overhauls. The kit's precise fit and high-quality materials make it a dependable choice for maintaining optimal engine health and performance.
