Billet head shell for the Kawaski 900 and 1100 engines. Includes head shell,brass fittings, and orings. Head shell is anodized for durability and protection against corrosion. This head is completely sealed by orings, no head gasket required.

NOTE: Aftermarket flame arrestors are required, as the water outlets are in the intake side of the ADA head and they will interfere with the stock airbox. You can also rotate the stock air box 180 degrees in some cases.
