I've never looked at a BMW.
Hopefully this pic will give you an idea of the tach. There is a thin line across the display that registers revs. I just ignore it.

I also included my ancient ice pick that I used to adjust the headlight. A screw driver is supposed to do the job but I never figured out how a fat tool should fit in a very small deep hole.

Thumbs Up

Bought this one for 40€:

Works great. Connected the red wire for 12v power to the horn (added a fuse box with 10A fuse), black wire to the bolt between the coil terminals for ground, and the green one to the negative terminal of the ignition coil. Adjusted the number of the cylinders so it doesn't double RPM. I only need some kind of a handlebar bracket to make it look a bit better.

Looks like a little L shaped bracket with a hole in either end should do the trick. I reckon you should be able to pick one up at any hardware store.

I used screw mounting the turn light - its further to the right so not causing the tach to be mounted angled

That's even better. Thanks.

Its mounted using screw mounting turn light bracket.
I have small update. This tach lasted me about 2k miles and while running at high speed on the highway - it broke from vibration. Something internal - holding the indicator needle went loose and tach now works erratically and buzzes from time to time as rpm increases. I decided to replace it with fully digital one - also from Ebay - unit that combines digital tach and voltmeter.

How's the digital tach holding up? I'm planning to add one to my bike, too (or possibly swap out the speedo with a digital speedo/tach combo unit).

The problem with it:
- not bright enough to view in full sun light
- also left whole day in sun light it started to melt the blackout film that is over the segments to make the appear black.


Please note lower left in voltage area - discoloration.

BTW: My voltage shows 10.8 volts and it is actually correct. Investigating why I have such voltage drop in the front light where I attached the meter. it is 12.3 on the battery.

The voltage drop is simply from the wire resistance, your headlight draws several amperes so part of the battery voltage gets lost as heat in the wiring. To get a better reading, connect the wires closer to the battery, or on a circuit that doesn't draw much current. At the horn, the voltage only drops a bit when you honk. The yellow wire at the horn is 12V, I connected the +12V (red) wire of my tach there.
