    This broke my timing chain..Ideas what it is please?

    Hi all. Timing chain snapped in my 650. No damage to piston or head, Valves and everything ok but when the chain broke it punched a home in the valve cover. This was between the cam chain and gear at the top. No idea what it is. Any gurus know what it is? Help much appreciated :) John
