Went to the dealer a while back for it( its the sensor on the oil feed line at the head) but they had no idea what i was talking about. They sold me another part with different tolerances and now the oil light goes off at low revs. I have lost the original part and was hoping someone could tell me what the number was, though you will probaly have to take the piece off.Or if you know where i could get an exact replacement. Someone help please!!
