It is possible to connect a rev counter with a MVT ignition but it needs a model 4-stroke at induction. Indeed a MVT DD or PREMIUM ignition has 2 sparks per revolution and a 2-stroke rev counter would double the actual measurement (the 4-stroke model divides the measurement by 2). Then do not directly connect the rev counter to the high-voltage spark plug wire because the ignition generates 42 KiloVolts to the spark plug and there would be too many…
