+1 It comes on when you turn the ignition to on... Then when you start it it goes off? That is normal... All you care about is, when running you do not have a light...THE OIL PRESSURE LIGHT WILL BE ON IF THE BIKE IS OFF WITH THE IGNITION ON, NO OIL PRESSURE, SO THE SENSOR GOES TO GROUND, THAT'S NORMAL. ONCE THE BIKE IS STARTED IT SHOULD GO OFF RIGHT AWAY, IF IT STAYS ON OR GOES OFF AND THEM COMES BACK ON THEN YOU HAVE A PROBLEM..SO IF I UNDERSTAND CORRECTLY WHAT YOU ARE SAYING IS IT COMES ON WHEN YOU GO TO START THE BIKE, AND IT GOES OFF WHEN THE BIKE IS STARTED THEN THAT'S NORMAL.
