I'm replying to my own post!
OK, I had a friend come over a few weeks ago and show me how to get the bike onto the stand. He said to make sure that both feet of the stand are firmly on the ground. Then it was just an authoritative bit of a pull and up it went. I practiced it a few times with him standing right there in case it tipped over. Never had a problem. And for reference, I am no gym rat at all -- 5'6" woman, 62 years old.
He made me thump on the bike, bump it, and try to knock it over. It is hella more secure on the center stand than on the kickstand, IMHO.
The biggest problem with the stand happened to me today. I rode for the first time since my neighbor showed me how to use the stand. When I tried to rock the bike backwards off the stand, it just refused to budge. Well, it scraped along my garage floor a bit.
I finally realized I had to push the ^%!$(#^$@ bike FORWARD to get it off the stand. DOH! There seem to be no limits to how many ways I can mess something up at least once!
