Plug in a digital voltage gauge in the lighter socket and see if it is jumping all over while you drive to rule out the VR.
If all normal for charging volts, then maybe the tach itself is going out. If you tap the gauge does it behave normally? Mine will stick if I leave the car in the sun too long. Plastic gauge face needs a tap and all good again.
Make sure you have good continuity from purple/black at CDI 6 pin connector to the back of the gauge. (Wiggle harness around while checking)

Thanks Dennis.
I'll try those suggestions. Before your harness, I would randomly get the needle stuck at about 3,000 rpms, tapping the gauge I could get it to drop a little, but it would just stick there for a while until it would just randomly start working again. If the voltage checks out, I will try to swap tachs with a friend.
