Hey everyone, I’m in the final stages of my ‘83 K100 restoration and finally fuelled her up and got her running. Problem. I noticed the speedo needle was occasionally flickering or bouncing, sometimes as high as 40 or 50 kph while at idle and in neutral. I popped her into gear and there was no speed registering on the gauge. Nadda. I removed the sensor and did the soldering iron test, and it was perfect, showing around 60kph as expected. The pick up is spotless and the FD oil is fresh. Any ideas where to go next?
Thanks in advance
Thanks in advance
