    This is related to the electronically actuated powervalve on my wr200.

    Am having *huuuge* dramas trying to get my powervalve set up right. One
    of the cables from the actuator to the valve recently snapped, making
    the bike run like a three legged dog. After replacing this cable. (which
    is exactly the same length, and in exactly the same position, as the
    last one) I'm unable to set the valve in the correct position. It's
    almost 90 degrees off. Does anyone know if it's possible for the
    electronic actuators on these things to go out of whack? I wonder if it
    got sent a bit off course after having no tension on it due to the
    snapped cable.

    I'm following the manual exactly, I've had a knowledgeable mechanic mate
    look at it, I've fiddled with all sorts of possibilities, sworn at it
    for 3 hours straight, but nothings working.

    Any suggestions?
