COMETIC Top End Gasket Kit for Honda C3187-EST, 66 mm - Engine Rebuild Seal Set

Top End Gasket Kit - 66 mm - Honda

The COMETIC C3187-EST Top End Gasket Kit is designed for Honda motorcycle engines with a 66 mm bore, providing a comprehensive solution for top end repairs. This kit includes a high-quality MLS head gasket, base gasket, and cylinder O-rings, along with other essential seals needed for efficient removal and reinstallation of the top end components. The MLS head gasket features a multi-layered steel construction with embossed outer layers coated with Viton rubber, ensuring uniform torque distribution, reducing bore distortion, and enhancing piston ring sealing for increased power output. This design is well-suited for high-performance, naturally aspirated, and boosted 4-stroke engines, meeting the demands of today’s high-horsepower, high-cylinder-pressure applications. The EST (Extreme Sealing Technology) gasket kit also includes embossed stainless steel head, base, and rocker gaskets covered with a proprietary rubber material, which helps draw heat away from the combustion chamber and dissipate it evenly across the gasket surface. This prevents hot spots and mitigates gasket failure, extending engine life and maintaining optimal performance. Crafted in the USA, these gaskets are engineered to withstand the rigorous conditions of modern high-output engines, ensuring reliable sealing and peak efficiency. Compatible with Honda models that utilize a 66 mm bore size, this kit is an essential upgrade or repair component for motorcycle enthusiasts and professional mechanics aiming for maximum engine durability and performance.
