I've also tried draining the oil with the bike on the sidestand.
Bwa Ha. Gotta laugh. It takes the pain off every time I've spilled oil all over the place while changing it. My worst was changing the oil on a 12 qt capacity aircraft engine. I dutifully drained the oil, and started refilling the sump while standing on a ladder from a gallon can. When I looked down as the can was emptying, I noticed a great flood of oil all over the floor. I had forgotten to close the drain valve! Not the first or last time I made a mess of that job though!My drain pan sits easily under the bike with the center stand down. I don't have any trouble rocking it on the center stand. Works fine. I get a bit over 2 qts out when I drain it.Bare
Now, as you all know, I would never do anything to damage the environment. I can say the termites don't like the ground around my wooden fence posts though.
