This Honda CB750 Four tachometer is back to life. 😎
After the initial restoration, the gauge developed an unusual damping issue. The most likely cause was that the instrument had spent too much time upside down during transport, allowing the damping fluid to migrate away from where it was needed.
With Tom’s help, we quickly identified the cause and arranged for the tachometer to return to my workshop. After correcting the issue and thoroughly testing the gauge, it was sent back once again. This time, the package was marked with additional handling instructions in Tom’s native language to help ensure it remained upright during transport.
The result speaks for itself. Smooth needle movement, accurate readings, and another classic Honda back on the road.
A big thank you to Tom for his patience, assistance, and for sharing this video of his CB750 Four.
