The L-twin layout of the motor does make for a long(ish) wheelbase, hence it will feel stable. I have a 749s that I have not really tweaked at all (suspension wise). It was set up by Italia in Lincoln and I reckon they did a pretty good job too. There is so much you can do with the damping, preload and ride height, plus the tyre profile as suggested above that I think you really ought to explore that before taking the fiarly radical step of altering the rake. oh, and a little couter-steering goes a long way!
