What are some good and bad for turning all the rebounds and compressions to high on the my gen 3 ....
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.
