Still waiting to hear back from Dime City. It's only got 1,200 miles on it, I've had it maybe a month and a half. Just using a regular 1/8" thick rubber washer between the mounting bracket and triple tree mounting point. Drive cable has nothing to do with the needle being stuck off the face. Like I said, odometer works just fine and it is screwed all the way in.
Gonna call tomorrow if I don't hear back in the morning. Thanks guys.
