    Anyone have a easy test for the cable. No needle movement except from vibration on yesterday's first test ride, and we all know the mess that getting to the input is inside the headlight bucket.

    Maybe take it off the speedo side and see if it is twirling when you ride...

    If you remove the cable from the transmission end and spin it, you won't know if it's the cable or speedo if still nothing happens. I'd think there's no way around it, the best test is removing the cable from the speedo end and try to rotate it. If it won't, then most likely it's good. Or, start up the bike on the center stand, put it in fourth and watch for the turning end.

    I'm sure cables break, but it seems more often to be the gauge.

    A trip into the headlight bucket reveals the last eight inches of the cable to be broken off. Cool, maybe a new cable and that's all she needs <:-)

    In my case it was the gauge that broke the cable. The gauge seized up which stopped one end of the cable from turning while the other end kept going. You might want to bench test the gauge before heading back out on the road.

    Try turning the input to the speedo counter-clockwise. That's its normal direction of rotation, though I'm sure if it's jammed, it won't turn either direction.

    Feelin' pretty lucky here, the cable spins freely and the needle blipped to 10 mph...
