    Thats a powervalve coupler. It goes between the left and right valve so both will open.

    just make sure when you reattach the coupler that both shafts are turned either up or down so the move together when joined by the coupler!

    Thanks guys for all the helpful information. I will give it another try tonight and see what happens. Just curious, what is the purpose of the waveeater clips ? And what else would you guys recommend for performance and handling that wont cost me an arm and a leg.

    The clips hold the PV pin in place and keeps it from walking out and your PV from dropping into the exhaust port and hitting the piston.Intake grate,ride plate,seal the pump.Not sure if you really need a tunnel reinforcment on a stock GP800 though.
