The Cometic MLS head gasket for Yamaha TX and XS 650 (1974–1982) fits an 81mm bore at .045" thickness and delivers dependable head sealing for rebuilds. Its multi-layer steel design pairs embossed AMP-coated outer layers with an uncoated stainless shim to match different surface finishes and loads. The center layer can be varied for thickness, needs less clamp load to limit bore distortion, and helps distribute clamping forces evenly across the seal.
