Brian,  whose

"odometer works fine, but I notice my speedometer needle bounces now -
not wildly - but it didn't bounce at all before...."

Try doing a cleaning and lubrication job and smoothly realigning the
cable housing of your speedo cable.  I've had this problem a couple of
times, and generally that's all it took to fix it.  Your FLAPS should
have graphite lube for this purpose.

Good luck
