Looking at installing the MotoGadget MotoScope mini on my bike in the next little while and will be giving this a go. Thanks Bob!
Someone asked me about this and I thought it would be useful to make it generally available:
When installing a Danmoto 180 or any other instrument panel which requires a trigger signal for the tachometer connect the trigger wire to either the blue or yellow wire at the coils. If the tach needle jumps around erratically adding a resistor of approx. 10K ohm in series usually fixes the problem (I needed the resistor on the GoldWing but did not on the 650)
