I finally got a Dyna at a price I couldn't turn down. Naturally it has a few problems and the speedometer shows that I'm running 90mph while in neutral. I've cleaned the sensor and the needle now jumps all over the dial, sometimes going completely around the face. So I'm now trying to find a replacement and I'd like to know if anybody has a stock number for the speedometer and any suggestions where I can find a replacement. I've found a '97 new Sporty speedometer on Ebay and I was wondering if that would work as a replacement. Thanks!
