Re: Speedometer issues

A new mechanical speedometer costs and arm and a leg. I sent mine out for replacement of the needle bearing for about $180 about six years ago, and they did a good job.

These things are delicate instruments with very small parts. They work on a balance between the force of a coiled spring and the torsion created by spinning magnets. Getting it just right isn't easy.

It's possible that your problem is just a small piece of dust in the needle bearing. You could try to blow it out with pressurized air, but be careful doing that. You could damage the coil spring if you blast it with highly compressed air.
