What is the function of the pluse generator. I have a 1985 GW 1200
is there two and are they located in the timing belt area?

I believe that they relay the position of the crankshaft to the ecu so that the ignition timing is correct (i think)

Yes John,there are 2 in the t.belt area,and Mark is correct,they tell the ECU where the crank is for spark for each bank.On a car,they call them what they do,crank position sensor,or cam position sensor.
