I had to go to the speedometer shop when I got my 95 tracker to get it working. all they did was took the tip of the cable off and slipped the inner cable out, dipped it in heavy grease ( looked like red bearing grease) and put it back together. I also had they check the spedo. head and he said it was good. it is a little jumpy at 20 -30 MPH, but it works good.
