I drained what I thought was all of the oil out of my Bonneville before ordering valve shims and seals and heading off for a trip. It was warm when I let it drain, about 30 minutes after running, and it had stopped dripping after quite some time.

I hand-tightened the drain plug just so I wouldn't misplace it, figuring nothing more would come out, but put a towel under the bike in case it dripped. When I came back home, the towel was soaked, and there was a rivulet of oil that had extended down past the bike. Quite a bit more had come out. I think I'll pull the plug when it's warm, but let it drain overnight from now on.

I think that this is the reason engines get "over filled" , not all the old oil had drained out.

Give the engine a tinkle to tease the rest out.

Really, I just walk away from the drip and return at some random later time and refill. Never been a known issue.

Under normal use, a 100 mL of old oil will not do harm for an engine like this - it is not surgical equipment or anything of the like.

^^ +1, exactly... a drop of oil or two, will always stay there, not elsewhere

I think I see an "echo" in your comment.

You actually WANT a tiny drop of oil to remain within the engine, to aid lubrication immediately after an oil change, when the full amount of oil hasn't yet circulated.

lol motorcyclists have the ability to take something so simple and make it so complicated

By the way, what kind of oil should I be using?

What you concern yourself with, gets big.

Organic , gluten free oil .
I probably opened a can of worms ( I mean oil ) but it was a good article in a VERY good magazine .
