Salaam to All:
I have managed to installed tachometer in my 70 CC bike. Actually it was made for CAR and now in bike it is showing some RPM when engine is running.
I made tachometer as 1 electrical pulse per revolution and it is showing 4000 RPM on idle which I think is not correct for bikes (correct me if I'm wrong) so it requires some calibration for proper working.
Can some body tell me what is pulses per RPM relation for 4 stroke 70 CC bike or what is calibration factor when using car tachometer in bikes.
