Default Calibrating speedo

I'm trying to calibrate my etb speedo, it's wired up to the electronic speed sensor in the mt75 box.

Currently it's set at 4000 pulses but appears to read roughly twice as fast as it should!

Does anyone know what the ratio is for the gearbox speed sensor is and how many pulses per rev the sensor does?
