I have run a kart tach on my WR200,and old KX80

All they use is a wire that wraps around the plug lead, and it picks up the impulse and displays.

You would just wrap it around one plug lead and presto.

You cold even get a whole computer, like an ALFANO. You can have speed, tacho, exh temp, water temp. Just like a mini MOTEC. THey are back lit, and look a bit like a MOTEC dash
