Caution: long post.
Problem: My oil level is higher in the sight glass after the first long ride vs. after just changing the oil. I don't understand why the engine acts this way. No other vehicle I have ever owned has done this.
Description:
When I do an oil change I fill the crankcase with about 6 oz. less than the recommended amount; run the bike for a few minutes to circulate the oil through the filter and check for leaks; let the bike sit for half an hour; then check the oil level. Usually the level is about in the middle of the two marks on the sight glass.

Here is the part I don't understand. If I fill the bike up to the F mark at this point it will be over filled after a 30 minute ride, so instead I fill it to the before picture. After a 30 minute or more ride the bike will be sitting at the F mark (after picture). Why does it get higher after a longer ride? It will not get any higher on subsequent rides. It stays at the F mark.
The only thing I can figure is that the oil is migrating from the transmission. I thought the migration was the other way though. Crankcase to transmission.
I always change the oil in my transmission at every oil change. I don't measure the transmission oil. I fill it via the fill hole and let it run out until it stops dripping. At that point I figure it is full. Am I overfilling the transmission? The bike is on level ground when I change the trans. oil.
Thanks.
