Hey! I have an 86 K100RT and had the same problem, make sure all connections are clean from the final drive pickup through into the instrument panel. Lots of problems with this design, plenty of fixes listed here too, but I found that my final drive pickup was shot, and replaced it for 40 bucks, works like a charm! good luck!

Hi There,

I had the same problem and it turned out that a good clean with a cloth of the sender unit in the final drive was all that was need to get it working again

It could be your pickup sensor on the differential, but first try to tap on your speedo when riding. If it starts working, the problem is in the cluster.

The most common problem is corrosion on the contacts inside the instrument cluster. You have to open it and clean the contacts indicated by the red arrow.

On the download section you can find a very good page explaining how to open the speedo.
