Put it up on the center stand, put it in thrid gear, and roll the back tire.
Maybe the compression will trigger the oil to drain?
Or maybe this is all a bad idea.
(Neutral Finder), i tried this in the past just to see if i could do it and never could, maybe i could with a second person spinning the wheel while i try to pop in 2nd.
I solved the oil problem and my bike is running fine with fresh oil and filter.
NOT a good idea at all but i bumped the starter a few times and nothing happened so i just let the engine start for about 1-2 seconds and the oil came gushing out about half a quart so i turned off the engine and the flow stopped, i have a 5 quart bucket and the bike holds 3 so i start the engine again and let it fill almost half the bucket with my hand on the kill switch i shut it down soon as the oil light came on witch was right around 2 & half quarts.
So really my oil is not completely fresh, i still have a half quart of old oil in there that mixed with the new oil..
some of you had what seems to be good suggestions, like maybe a strange vacuum problem, but how can that be with both drain plugs completely out including the oil filter.
i also thought about sticking a straw or something up in there but what if it knocked something loose, there is no way i can tear down the engine to fix it.
I still would like more feedback on this, maybe from that lawnmower guy
