Cometic 99-02 Yamaha YZF-R6 68mm Bore .030 MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 68mm bore and is .030 inch oversize, making it a solid choice for your 1999-2002 Yamaha YZF-R6 rebuild. MLS gaskets are known for their strength and ability to handle higher compression ratios and temperatures compared to traditional composite gaskets. The multiple layers of steel, often with a specialized coating, allow this gasket to conform to the cylinder head and block surfaces, creating a strong seal even under demanding conditions.

When you're rebuilding the top end of your Yamaha YZF-R6, a properly sealing head gasket is critical for maintaining compression and preventing coolant and oil from mixing. This Cometic gasket is designed to fit precisely, ensuring that your engine's combustion chambers remain sealed and your cooling system functions as it should. The .030 inch oversize bore is important to note; it's intended for engines that have been bored out to this specific dimension to increase displacement.
