Worn tappet blocks can affect cam timing, and cause tappets to wear on the guide faces. Wear is especially a problem in alloy cylinders with alloy tappet blocks.
Made from U.S. mill certified, high nickel bronze alloy these will directly fit 1969-on 650 and 750 engines.
They can be modified in a lathe to fit all earlier 650 twins including pre unit 650 and 500. If you are building an engine and the valve train has to be accurate, don’t take chances with old cast iron or low grade aluminum blocks!
