Not sure, but I'll put my 2 cents (Pence?) worth in anyway...

Depends on the Tacho...

If it's mechanical, then I doubt it will work, because (as far as I'm aware) there's no drive mechanism on the engine for a Tacho. Many older bikes run the tacho drive from the camshaft and would require the correct ratio as you mentioned above.

If it's electronic, then it may work, but I've no idea what ratio it would need to be. Welcome to the world of modifying bikes!

Many aftermarket Tachos run a sensor wire from the coil so they pick up a signal everytime a spark "happens" and convert it to a reading on the tacho. Not sure if there's any ratio required with them.

First step is to find out from the supplier if it's mechanical or electronic...
