You will not find a suspension setup that will work "correctly" for carrying a passenger and for NOT carrying a passenger without having to make adjustments.
Theoretically, when you carry a passenger, you should increase rear preload (by a lot) to minimize the change in rear ride height (which affects the steering a lot) and it will most likely want stiffer compression and rebound settings. The moment the passenger jumps off, the suspension will now be wrong for NOT carrying a passenger.
What most people do when carrying a passenger (including myself) is NOT make any adjustments and just ride a lot more conservatively so that the screwed-up steering doesn't cause a problem.
If you are going to be carrying a passenger most of the time, then perhaps it might be worth optimizing it for the passenger-carrying conditions ... but an even more appropriate course of action might be to get a different bike that has better passenger accommodations ... I regard sport-bike passenger seats as "emergency use only", hence no suspension adjustments warranted, just ride slower and carefully so that you both get home.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
