Cometic C8141 Copper Cylinder Base Gasket - 020 for 1157-1260cc

The Cometic C8141 is a precision-engineered copper cylinder base gasket designed for high-performance motorcycle applications in the 1157-1260cc displacement range. This .020" compressed thickness gasket provides exceptional sealing performance for modified and racing engines where precise deck height adjustment is critical.

Key Features:

• Solid copper construction for superior heat dissipation and conformability
• .020" compressed thickness allows precise cylinder deck height adjustment
• Designed for 1157-1260cc displacement engines
• Ideal for high-performance and drag racing applications
• Conforms to irregular surfaces for reliable sealing under extreme conditions
• Reusable with proper installation and surface preparation

Copper base gaskets are essential components for performance engine builders seeking to optimize piston-to-head squish clearance. The malleable copper material provides excellent sealing on properly prepared surfaces and withstands the demanding conditions of racing and high-boost applications. For best results, surfaces should be machined smooth and flat, and proper torque specifications should be followed during installation.
