Due to the Long Reach / Deep Set spark Plug design it was impossible to find a Piston Stop Tool - until now - MMR went to work on this purpose built tool! Simply screw in just like a spark plug using a spark plug socket or 3/8 rubber hose and find true TDC enabling perfectly degreed Camshafts. Aluminum Contruction prevents marking up or damaging the piston like those manufactured from Steel.
