Cometic Yamaha FJ1100 3.460 .005 Copper Base Gasket

This Cometic C8240 gasket kit includes the specific copper base gasket you need for your 1984-1985 Yamaha FJ1100 or 1986-1993 Yamaha FJ1200. A well-built gasket is crucial for maintaining proper compression and preventing leaks between your engine block and cylinder head, ensuring your motorcycle runs smoothly and efficiently.

Crafted from copper, this base gasket offers good thermal conductivity and conforms well to sealing surfaces, which helps create a strong seal under the pressures and temperatures found in your engine. The .005 inch thickness is a standard specification that works with many engine builds, and the 3.460 inch bore size is specific to the FJ1100 and FJ1200 models. Proper installation is key to its performance, so make sure your mating surfaces are clean and flat before assembly.
