Yeah get a back stand. I do it the cheap way tho, I kneel next to the bike and ease it off the kickstand slowly, stabilising it, then I lean it back over on the stand slowly after I am done looking at the oil glass.
I wouldn't put it on a stand to check oil, since that will raise the rear and oil will go farwards, making the oil level seem lower than it really is. Just put a piece of a 2x4 under the kickstand and it will be practically level but still leaning on it enough to not fall over. That's what i do when I need to put it up on a stand by myself anyway.
