C9116 Top-end gasket kit. XL1000 Low CR

For riders looking to drop the compression on their Ironhead Sportster, this Cometic Low CR top-end kit is the ideal choice. It is specifically tailored for 1982 to 1985 XL1000 models and features thicker .063-inch low compression copper cylinder head gaskets paired with .031-inch copper cylinder base gaskets. This setup is perfect for specific tuning requirements or dealing with lower octane fuels while maintaining a reliable seal. The kit is sold as a set and includes all the necessary gaskets, seals, and O-rings for a complete top-end rebuild. Cometic's copper gaskets are a favourite in the workshop for their durability and superior sealing capabilities on vintage Harley-Davidson engines.
