C9756F EST motor gasket kit

This Cometic EST motor gasket kit is the definitive solution for a complete engine overhaul on 1986–1987 XL1100 4-speed models. Sold as a set, this package includes every gasket, seal, and o-ring required for a full reassembly, including the primary gaskets. The kit features Multi-Layer-Steel head gaskets at .040" thickness, which cleverly eliminate the need for dowel pin o-rings. The base gaskets are constructed from .020" Single-Layer-Steel with a high-temperature Viton coating, providing a seal that won't weep or tear. You also get durable rocker cover gaskets and exhaust gaskets designed to maintain perfect flow without fraying. To round it out, the included valve seals use Viton rubber and outer springs to ensure your top end stays tight and reliable for the long haul.
