Hello I’ve just bought a 1981 gs550t. The engine has been rebuilt and seems to run very well. I’ve done a couple of hundred miles with no problems. However the other night I opened it up a bit, not a lot only around 65/70 and the oil light came on and now comes on all the time. The oil is almost full and looks new. Is the light a low oil pressure light or low oil light? Any suggestions please, don’t want to ride it with the oil light on.
