Motojitsu has a good explanation of the how's and why's simply called "how to adjust your rebound dampening" (he also covers compression and preload). But basically you adjust the rebound in the rear so if you bounce your weight on the tail and stand back up (or push with your hand while holding the bike upright) it bounces back without coming up past it's normal resting point. My SR came from the factory very soft. I'd bounce my weight on it, and the tail would kind of "sink" upwards. You adjust the rebound to the point where it's actually bouncing past the resting point then resting back down....then dial it back so it bounces back as fast as possible, without going past it's resting point. The front, you're adjusting it so when you hold the front brake and push on the forks (then immediately stop pushing), it bounces back, then past the resting point MAYBE half an inch, then rests. If you do these two adjustments, the tires will track bumps a lot better and your rear has a much lower chance of torquing the belt.
