SpecialK would attest to this.

My speedo bounced like crazy. We had discussion about how to remedy it. We did not agree. 200 miles later it does NOT bounce at all.

I fixed it. Actually it fixed itself.

Mine employed a speedo-reversor. It is called that, but what it really is a 90 degree adaptor. It is pre-greased. NOT ENOUGH.
The cable is dry as well.

If I am not mistaken the best thing to use is powdered graphite, or graphite based grease. I had neither. I used Lubriplate. I suppose any white grease should do. You don't need much.

It kept on bouncing even after the lubrication. Only at slower speeds. Then it started doing it at slower speeds yet. Slowly but surely it started giving me stable readings at anything over 15-20 MPH. Eventually stopped bouncing at all speeds.

My take is, the brass drive componets in the reversor started smoothing out the machining roughness, and the grease started working it's way down the cable.
