Last week I pulled the drain plug when the bike was hot planning to put oil back in the next day. About 6 hours later a friend called and I needed to get another bike out RIGHT AWAY but the FJR was in the way. Thinking all the oil was out I rolled the FJR out of the way and left it on the side stand. I came back home to a BIG MESS on the garage floor. i'm guessing 5 ounces or so. Does that answer the question?
Ah, your pain is our gain.

Well, it appears that rolling your FJR with the drain plug out causes more oil to drain out.

Seriously, your experience indicates that the side stand allows a few ounces more oil to be drained. However, I don't really think it matters. As Redfish said earlier, there will always be some old oil left in, you can't get it all out.

 
FWIW, my '75 GL1000 actually had little cup dealies cast into the cylinder heads such that the cam lobes would be lubricated on startup. The side effect, of course, was these things never drained when changing oil, unless you removed the valve covers and emptied those little reservoirs when changing oil (and presumably refilled with fresh oil).

I figure engines have lots of little crevasses in them that hold onto a little oil when drained. This relies on this "old" oil being little enough of a contaminant to be diffused with new oil and not be a problem. For sure the inside surfaces of the engine/transmission components would retain a film of oil, which probably amounts to quite a bit. Hard to get obsessed over the possibility.

 
An old mechanics trick before detergent oils became common was to add kerosene to the oil before a change then let it idle for 15-20 minutes. I did it a few times to my 64 VW beetle dune buggy back in the day. Note, I said add it to oil, not instead of oil. Of course I usually used recycled oil that was sold in glass bottles for 5 cents a quart.

Yeah, we did that back in the day with my brother's '67 bug and all our dirt/sand bikes. Kerosene wasn't too popular where we were so we used #2 fuel oil, nearly the same thing providing the same result. Add about 25% the oil capacity and idle for 5-6 minutes until warm. Drain and refill as usual. Never had a problem. Ever. But like I said, those vehicles were used in extremely dusty and muddy environments, the kind where you have to blow out the air filter every other day to keep from choking down the engine with fuel.

 
Side stand for me. Use some shaped aluminum foil to direct the flow off the plastic. Don't listen to these guys, they hate everything. Moving a post to NEPRT is a badge of honor.

After reviewing your question, we find that if you really wanted to know you would have already tried it for yourself. When you care enough to measure the difference, please let us know. We are all dying to find out.

 
And sarcasm is one of the reasons I enjoy this place.

Now, Mr. OP, you could probably redeem yourself by following Mr. Hunter's advice two posts up. Measure the difference and let us know.
