As has been said a few times, if your motor blows oil out the breather something is wrong and I would address that. It should not be considered "normal".
It may be an issue with the motor or it may be too much oil in the sump. But whatever it is, it is not "normal".
There is nothing weird about a Guzzi motor. They do not work under different rules of physics and engineering than other motors. And many motors do not have a method of separating oil out of the breather air, yet they don't blow oil unless something is wrong.
Yeah I'm pretty sure my oil has been over-filled! Checked it cold last night and it was almost to the top of the flat part of the dipstick. Then I went for a ride and checked it warm and it was over the flat section by half a cm...
