If you are looking for maximum performance from the Q2, Dunlop says 28-30 rear 30-31 front (cold) depending on outside air temp. However, you shouldn't be riding hard enough on the streets to need max performance. Your Busa is heavy as well as you so I'd suggest 34-36 cold pressure in both ends.
34-36 gives you a nice balance between handling and grip. The lower pressures will give more heat in the tire as well as a bigger contact patch. The down side is slower turn in and heavier steering.
The higher pressure gives quicker steering while giving up some grip due to less heat accompanied by a smaller contact patch.
Choices in tire performance is a balancing act. In order to gain in one area you must give up something in another area. As my daddy use to say "There are no free rides".
