Adjust the Preload on the high end to start with, and the rebound to the hard side of things. I weigh 265# plus gear, and run the preload pretty much all the way up (one or two clicks from full, just to be different) and the rebound is 1/4 turn from full hard. Nice ride, matches the front end pretty well when not loaded up with full cases and a tail bag.
Play with the settings, ride for a few days, make a change, see how it feels. It's not hard and fast, but something that you feel in the seat of your pants when things are adjusted correctly for your style.
