Cometic Top End Gasket Kit - C7798

Ensure peak engine performance and reliability for your Yamaha Raptor YFM 660R with the Cometic High-Performance Top End Gasket Kit. This comprehensive kit provides all the necessary seals and gaskets for a complete top end rebuild, engineered for superior sealing and durability.

Description

The Cometic High-Performance Top End Gasket Kit is meticulously engineered to meet the rigorous demands of high-output 4-stroke engines, specifically designed for the Yamaha Raptor YFM 660R and Raptor Limited Edition YFM 660R LE models from 2001-2005. At its core, this kit features advanced Multi-Layered Steel (MLS) head gaskets, a hallmark of Cometic's Extreme Sealing Technology (EST). These gaskets are constructed with embossed stainless steel outer layers, coated with a proprietary Viton rubber material. This innovative design ensures an even torque load across the gasket sealing surface, significantly reducing bore distortion and promoting a better piston ring seal, which translates directly into more power and improved engine efficiency.

Beyond the head gasket, the kit includes correct base gaskets, cylinder O-rings, and other essential top end-specific O-rings and seals required for the removal and reinstallation of your engine's top end. The specialized head gasket material is designed to efficiently draw heat away from the combustion ring and dissipate it evenly across the gasket surface. This crucial feature eliminates dangerous hot spots and prevents premature gasket failure, even under extreme operating conditions. Manufactured with pride in the USA, this Cometic gasket kit offers unparalleled quality and reliability for your high-horsepower, high-cylinder-pressure machine.
