Top End Gasket Kit - 66.50 mm - Yamaha

The Cometic C7275 Top End Gasket Kit is designed for Yamaha models with a 66.50 mm bore, providing a comprehensive solution for top end repairs. This kit includes the necessary base gasket, head gasket, cylinder O-rings, and other essential seals to ensure a proper rebuild. Crafted to meet the demands of high-performance engines, these 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. The gasket's multi-layered steel design features embossed outer layers coated with Viton rubber, making them suitable for today’s high-output 4-stroke naturally aspirated and boosted engines. These head gaskets are engineered to withstand high cylinder pressure and heat, ensuring reliable sealing under extreme conditions. The EST (Extreme Sealing Technology) gasket kit includes embossed stainless steel head, base, and rocker gaskets, all covered with a proprietary rubber material that helps dissipate heat evenly and eliminate hot spots that could lead to gasket failure. Manufactured in the USA, this gasket kit guarantees quality and durability for demanding applications. Compatible with Yamaha models that share the 66.50 mm bore size, including various high-performance and boosted engines, this kit is ideal for engine rebuilds, top end repairs, or upgrades aimed at maintaining engine integrity and performance. Proper installation of this gasket kit will restore engine compression, improve power delivery, and ensure long-lasting performance in your Yamaha motorcycle or ATV.
