the setting for each bike will be different. there isnt any real guideline as a generalization for each bike. for instance, the kawasaki zx10, imo prefers a stiff set up. while (on another board) im racing the cbr600rr rm, and for infineon i had a really soft setup, like springs at 1 in the front, and 2 in the back. and the preload was 4 in the front and 6 in the back, the damping was rebound: 2f, and 3r, and the compression was: 1f and 2 rear. but at suzuka, on the same bike i run the springs at 7 in the front and 8 in the rear, obviously much more damping as well. so not only does the settings change from bike to bike, but also from track to track, on the same bike.
