[iron mustang]

hello. great site..
i have a question about the yammi 800 powervalve motor. does anyone know if i can install the gas powervalves on the 800 motor . it is stock motorwise . meaning it has a single pipe. any help would be appreciated

Hey Iron-- i replied to the same question over on the riva board
in cace you didnt see, you cannot use the gas valves with the stock exhaust on the 800---- there is not enough clearance between the pipe and cyl---- your best bet is to go with the billet valves, use the stock actuator arm with PV clips, which also has the downward stops to prevent piston to valve contact
