ABSTRACT:
A highly reliable, versatile and long lasting motorcycle gasket made of a special rubber-covered metal having dual raised silicone beads around the perimeter on both the front and back surfaces of the gasket. The raised silicone beads are provided around the perimeter of both the inner bore and the outer edge of the gasket to provide a double seal. Mirror-images of these same raised beads are provided on both the front and rear surfaces of the gasket further improving its sealing characteristics. A broad silicone layer is provided on both surfaces of the gasket in areas which correspond to known gaps in the metal parts of the engine with which the gasket is to be used.
