The Yamaha 5BE-11193-00-00 head cover gasket is a genuine OEM valve cover seal designed for four-stroke Yamaha engines. It is compatible with YZ400F, YZ426F, WR400F, and WR426F models and serves to seal the interface between the cylinder head and the valve cover, preventing oil leaks and preserving engine sealing integrity. Made from a heat-resistant composite gasket material, this precision-fit gasket mounts between the cylinder head and valve cover to maintain proper internal pressure. Common replacements include Yamaha 5BE-11193-10-00, 5EB-11193-00-00, and 5JG-11193-00-00.
