COMETIC C7044-EST Top End Gasket Kit for Yamaha 100mm Engines

Top End Gasket Kit - 100 mm - Yamaha

The COMETIC C7044-EST Top End Gasket Kit is designed for Yamaha engines with 100mm bore applications, ideal for high-performance 4-stroke models. This comprehensive kit includes a high-quality MLS head gasket, base gasket, and cylinder O-rings, along with other essential seals required for top end removal and reinstallation. The MLS head gaskets feature a multi-layered steel construction with embossed and coated outer layers using Viton rubber, ensuring optimal sealing and durability under high pressure and temperature conditions. These gaskets promote even torque load distribution across the sealing surface, reducing bore distortion and enhancing piston ring seal for increased power output. Suitable for naturally aspirated and boosted engines, the kit is engineered to meet the demands of high-horsepower applications, making it an excellent choice for performance enthusiasts and professional rebuilds. The EST (Extreme Sealing Technology) components include embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber compound that helps draw heat away from combustion chambers and dissipate it evenly, preventing hot spots and gasket failure. Designed and manufactured in the USA, the COMETIC C7044-EST kit is built to deliver reliable sealing performance, extended service life, and consistent engine operation for Yamaha 4-strokes in racing, off-road, and high-performance applications. Compatible with Yamaha models featuring a 100mm bore, including specific years and engine types, this gasket kit provides a comprehensive solution for top end rebuilds, ensuring your engine maintains optimal compression and power output.
