So I have been told, Ducati's work best the higher they sit, raise the bike bit by bit till it gets unstable on a straight, then back it off slightly and adjust the front so that it will turn but not run wide. The thing is that if you get faster you will have to adjust again as it will behave differantly.
Basicly, get it working so that you are comfortable, but remember as you get faster it will need adjusting again to get back to that comfortable feeling.
Always note any changes you make and note alongside that what differance it makes on track.
