Oil Level Before and After ???

[Solina Dave]

Maybe someone has an idea regarding my '78 GLs oil level. I stored my bike last October for the winter. I looked at it today 6 months later.
Prior to storage I changed the oil and filter. The oil level settled 1/16" below the top line in the sight glass. Then I ran the engine for 2 or 3 minutes to circulate the oil, and put it in hibernation.
Today I checked the oil level and it's 3/16" below the line. There's not a drop on the floor. Is the difference in the filter, or someplace else, or what?

Thanks..............Dave

Perhaps it left an air bubble in the filter due to the short run, or perhaps the valves leaked a bit into the cylinders during the long spell sitting still.

Part 2 of that sounds like a good possibility Fred. I was just checking out a few things on it today, prior to it's spring startup. Hopefully that will happen in the next day or so. It's generally very stubborn in starting after a winter layover, and it does burn off quite a bit of oil before it calms down, and runs smoothly. I have a feeling your right, and it is seepage into the combustion chamber. I store it on the centre stand in an attempt to prevent that somewhat, but it is getting old.

Thanks for that Fred........................Dave

You changed oil, checked the level and then ran it.
It simply flowed into the motor and tranny, hence 1/8" lower on the stick when checked again!

When I first put the oil in, wouldn't it fill the pan to a point on the sight glass, then circulate through the engine during running, and then settle back to the original level in the pan during the 6 month layover?

Was the 3/16 measurement on the same temperature engine. Hit and cold could vary that much.

[Solina Dave]

Probably about the same. Once on Oct.30/18, and then again yesterday. I can't remember the temperature in October, but me changing the oil, if it was cold out, would have been highly unlikely. I forgot to mention in the OP that a level of 1/16" below the top line was also recorded (cold) the day after running the engine.

1/8 inch is insignificant. It’s fine.
