Bouncing speedo fix

[BullittAndy]

This post is mostly for future searchers but any comments added are appreciated. I just completed #3 and it cured the last of my bouncing speedo blues.

Bouncing speedo fixes. I've used all three and each provided improvement.

1. Replace speedo driven gear.
2. Replace cable. (Mine was resting on exhaust)
3. Disassemble speedo gauge cluster and lube the speedo mechanism. Also the speedo uses magnets to operate and if they are not aligned then the speedo will bounce. I could hear scraping after I disassembled the gauge cluster and so kept tweaking and oiling it until it was silent.

It now operates perfectly above 20 and bounces slightly below 20.

Good luck.

Interesting comment about the magnets. Have you checked RPM to road speed to make sure the speedo calibration is good?

What did you use for lube?

The proper cable lube is a small tube of graphite compound. It is available at most auto parts stores. You are only supposed to lube the lower half of the cable. This prevents the lube from working its way into the head and gumming up the magnets & rotating disc.

That's for the cable, but BullittAndy said he lubed the speedo mechanism.
