i know i asked this before but only now do i have the beast on jack stands.

my speedo will work fine up to about 30-40 mph then start flying around from 40-120mph.

how does one diagnose the source of the problem? speedo cable or angle drive?

or should i just throw $ at it until the problem stops or a new more expensive problem shows up?

thanks...

J'aime les français, ils font de vraiment bonnes pomme de terre et les bonnes pâtisseries.

never mind, found my old post....

thanks...

Try another speedo to see if that works first.
If it does the same thing its probably the cable that has a kink in it.
The angle drive doesn't go bad unless you jack on it. They just leak oil.

Geoff's right. Bouncing is usually a bind the cable. Loading/Unloading causes the bounce.
