For owners of 1986 to 1990 XL Sportsters, this Cometic primary gasket and seal kit offers a modern sealing solution for older 4-speed models. The kit includes all the necessary o-rings, seals, and gaskets for both the inner and outer primary covers. These gaskets are made from Aluminum Foamet Material, featuring a sturdy aluminum core with a nitrile synthetic rubber layer bonded to both sides.
