Although you can (and did) get away with it, I wouldn't recommend it mate, unless you lay it over onto an old mattress or a heap of old blankets etc.
The alternator cover (on the left side) is only very soft thin alloy and the weight of the bike can damage it quite easily, and the points cover on the other side is only thin tin and will dent very easily, but worse, the engine casting on that side under the points cover is thin and brittle, and if you break that, you'll cry yourself to sleep for ever!
If I don't have a centre stand I use a couple of cheap jack stands under the rear footpeg hangers to steady it, and a jack topped with a small block of wood under the front of the engine to raise the front of the bike. Cheers, Terry.
