    Anybody have there power valve sticking open after getting into the high rpm's? Doesn't seem to close fast enough so i loose bottom end power.
    The valve seems to move freely when i checked it, could the govenor that controls it be sticking ?:confused:

    That happened to me. Sometimes stuck open, sometimes closed.

    I had to clean the valves on both sides very thoroughly to get them working properly.

    Use a really clean synthetic (like Motorex) and run it at 40 or 50 to one. Your valves will stay much more clean and free.

    My valve seems to move freely, so i don't know what would cause this.
    I looked at my CD manual and looked at the breakdown, is it the spring on the drive that controls the closing of the PV ?
