1981 R100RS
I noticed some lite smoking at the front of the engine (down by exhaust pipes) as I was warming up for my ride this morning....70 degrees.
I have not noticed this before and the red oil light was on briefly then turned off and did not come back on...oil is fresh and at proper levels.
I will keep my eye on this situation, but is this anything to be concerned about?
Thank you in advance for your comments.

You say red light for oil. Not totally sure on the '81 but on my '78 /7, the red light is for the generator...the oil pressure light is yellow.

I think the charge light is red and the oil light is yellow. St.

Not on my "modern " 1981 R100RT, both oil and alternator are RED. And my oil light goes out while cranking and the Alternator is out above about 1000-1200rpm. Unless it's a faulty oil pressure sender or wiring issues the light should never come on once the motor running, just cranking should extinguish the light once pressure builds.

I changed the oil today with Valvoline 20W50 VR1(high Zinc content) and new filter, 3qts. Did a test to see how long from a full drain, let sit for an hour draining, refill and cranking until the oil pressure light goes out. I pulled the plugs and grounded them to the heads with jumpers. With a full battery and counting one thousand one, one thousand two etc. I saw the light extinguish at about 16 seconds. The oil cooler had drained also but should not have been open since the engine was cold during the test.
