You can buy aftermarket electronic revcounters (tachometer) quite cheap.
If you are blessed and own the early model CA95, rigging an instrument up to show the engine revs is quite simple.
I once saw a Benly racer with what looked like a revcounter which was iluminated. Closer inspection showed it to be a speedometer with the red line marked on the glass face.
If anyone would like to go down this route, I can let you know the calibration details from one of my revcounters and the cables are available from you know where on Ebay. You then just need another speedometer.
Pushing your motor to 10,000rpm ain't a problem, it was designed to go there, it's when you start pushing it beyond that figure that problems occur.
