Ah, man no one can search... too lazy I guess

covered at least once just in the last month...

The over rev buzzer is adjustable by a pot on the back of the tach.

If you look at the circuit board on the back of the tach (not the gauges, but the actual tach itself- 4 screws and remove it from the gauge assembly to get to the circuit board).

Anyway on the circuit board there is two (yep that is 2) adjustment pots. You want the metal one. Each half turn is worth about 500 RPM.

But do not touch the plastic pot as that adjusts the calibration for the tach itself. Only the metal pot adjusts the calibration of the over rev.

But before you adjust anything make sure that the trailing coil is firing properlly, as your tach may not be reading correctly, and be your whole problem. You'll need to check the tach lead at the coil with a multi-meter or test device that reads tach signal before adjusting anything.
