A lot depends on your climate and the time it's going away for.
My XS650 will likely be ridden a couple more times this season, and then again no later than March. Might even sneak out on a dry day between now and then, so really, I don't 'winterize' at all. IMHO letting it sit for a few weeks between running isn't a big deal.
If longer though, I'd fill the tank, toss a little Seafoam in it, run it through the system, then drain the bowls (maybe, not 100% on this). Put it up on a center stand if you can, wipe it down with an oily rag (helps prevent rust) and call it a day. Lots of online writeups on winterizing. Some will have you dropping oil into the cylinders etc. which is all fine and good too, especially if you're not going to run it for the next 6 months.
