Cometic’s .030" MLS head gasket for Yamaha Roadstar (1999–2003) with a 102mm bore is made to restore durable head sealing. Multiple embossed layers combine AMP-coated outer faces with an uncoated stainless shim that allows thickness variation. The MLS construction requires less clamp load, reduces bore distortion and helps conform the sealing load across the head surface for consistent sealing performance.
