My understanding is that you can easily over-fill a Ducati engine and, if you are lucky, the excess will be blown out without causing any damage. At that point, about 3/4 full on the sight-glass, the level will be stable for many a mile. The ace tuners BSD at Peterborough told me this and drained some of the oil out of the ST4 when I took it over to them to cast an eye on, shortly after I'd bought it in 2003. Little did I know at that stage that one of the best Ducati mechanics, Carl Harrison, was much much closer to me than PE!

I guess different manufacturers have different ideas; some specify checking the oil level 30 seconds after stopping a hot motor, while quite a bit of oil is still in the various oil-ways. It all depends on what the sight-glass is actually telling you. Since we are dealing with Ducatis, I'd say go with the above advice.
