The Cometic MLS head gasket for Yamaha FJ1100 is specified at an 81mm bore with .030" thickness and constructed from multiple embossed AMP-coated and uncoated stainless steel layers. This multilayer design meets harsh sealing environments and varied surface finishes, requires less clamp load to limit bore distortion, and provides a robust replacement option for MLS-capable head-to-block interfaces.
