got a strange hang up on my speedo. I seems to work just fine up to about 70-75ish. Going beyond that the needle doesn't move. My GPS says I'm going faster. So I start tapping and slapping the side of the speedo pod and the needle will start to rise and eventually be close to the GPS speed (I know it's likely never to match perfectly). Then when slowing down, the needle doesn't drop. tap/slap again and it drops fast to the GPS speed and then works fine again. in the lower speed ranges.

Cable? dirt inside the unit? bent needle? magnetic pick up or something needs cleaning?

Is there a write up anywhere on cleaning/fixing these speedos?

Sounds like the needle could be hitting/rubbing on something around there. You could open it up and take a look. Maybe even drive it with it apart but connected and see if it still sticks.
Palo Alto speedometer can fix them but they are not cheap!
