Cometic 14-17 Yamaha FZ-09 .023 Head Gasket

This Cometic head gasket is constructed with multiple layers of steel, measuring .023 inches thick. This multi-layer steel (MLS) design is a common choice for modern engines because it offers a strong seal that can handle the pressures and temperatures found in your Yamaha FZ-09 or FJ-09's combustion chamber. It's built to maintain its integrity under demanding conditions, helping to prevent leaks between the cylinder head and the engine block.

When you're rebuilding the top end of your Yamaha FZ-09 or FJ-09, a reliable head gasket is crucial for proper engine function. This gasket is designed to fit your specific model, ensuring a direct replacement for the original part. Its construction aims to provide a consistent seal across the entire mating surface, which is important for maintaining compression and preventing coolant or oil from entering the combustion chamber or vice-versa.
