The Cometic MLS head gasket for Yamaha TX and XS 650 (1974–1982) fits an 82mm bore at .045" thickness and offers a resilient multi-layer steel seal for top-end work. Embossed outer layers with AMP coating and an uncoated stainless center shim accommodate harsh sealing conditions and a range of surface finishes. The center shim allows thickness variation, reduces clamp load and resulting bore distortion, and helps conform load distribution across the sealing area.
