    Help with Power Valve Motor

    OK guys, It is a 2000 GP1200R I know when you shut it off, the powervalves should cycle through. However Mine does not. I have replaced it with three diffrent PV motors, and 2 complete electrical systems. Still, will not cycle.

    it would only be one of those 2 things right?
    any other things that can cause that?
    what would I do to check?

    And they are not connected to the PV's themselves. So they are not froze up, and even if they were, it dont matter, there not connected.

    Thanks in advance to all who help.

    Do the PVs cycle when it is running?

    Hey Bill,
    I have not tried running it in the water or anything, I have not got past them not cycling after I start, then shut off. Should I try to drop it in the water and see if I can't get it up to speed? Or if I rev it up on the trailer, should it cycle there?

    What other mods have you done?

    Do you have an Advent CDI by chance?

    Duke only mod I see is a Stinger 2 pipe nothing electrical, no advent
    RX thanks for the chart, I will test that as soon as I can, although I have three PV motors, I would have to think all three are bad, and I did try them all. but I will check them just to make sure thanks

    If the motors check out good you might want to try a diff CDI just to be sure. Rare for the OEMs to go bad but they do on occasion.

    I agree Duke, but I did swap the complete electrical system, which I am pretty sure the CDI is in the ebox right, not like the 1300 where it is in the front, Correct?

    If it so happens it is the electrical box, I have a complete 1200 box with CDI for sale. It came out of my ski. All proceeds will goto the mudbug fund.
