I have a '93 WXC350 and had an '01 TE400 and as rancher1 says, pull in the manual comp release and kick through 6 times or so. I do this on a hot stall and bike starts right up.
I've never need to do it on a cold start though. I always found that the secret to starting a single cam, was get it just past TDC and kick it as slowly and deliberately as you can. I got my '93 a few years ago, with almost no time on it, because the previous 3 owners couldn't start it. Fired on the fourth kick and usually starts on the second now. Other thing.... I always drain the carb, when it's going to sit for more than a couple days.
I will add a little more on this, always drain the carb on the Ducati ignition models (1995-2002) if it is going to sit at all. The SEM stuff (1994-earlier) doesn't seem to mind for a while though but it is still a good idea.
