Rev counter
Is it possible to fit a rev counter to a 56 G80S.

Re: Rev counter
To fit an original chronometric tacho would be expensive (assuming you could find one in the first place!) and would require a replacement outer cam cover with tacho drive and probably a replacement exhaust cam. You would also lose the ATD, as these cannot drive a tacho. All in all this is not a realistic way forward but you can get modern electronic replica tacho from Smiths, see https://www.digital-speedos.co.uk/gauge ... meter-p212. These look the part but appear to fit straight on without the mechanical changes required by an original part and at £245 would be a LOT cheaper than a chronometric and drive. I have been considering one myself and if you take this route would appreciate your experiences. Andy

Re: Rev counter
Many thanks for the reply and info. Seems the one listed is out of stock at the moment so still looking for another solution.

Not a G80, but I fitted a tachometer to a Norton ES2 engine, which is very similar. I machined the mag/dyno chain cover to accept a cable drive gearbox. To drive it, I made an extended nut with a slot machined across it. That engaged with the tang on the gearbox. It all worked very well. I apologise for the quality of the photos, but they are the only ones I have. The engine was painted with a heat dispersant matt black paint. I've recently been thinking about doing the same to my G80CS. Adding a tacho, not painting it black.

The pics can be found by right click and opening in a new window. I suspect the site has hotlinking protection.
Can you not just fit a tachometer that takes pulses from the condenser/point etc.
