Solace, you worry WAY to much. The springs in your bike are fine. If you were, say 80lbs., or 350lbs+., then you might run into a problem. Unless you plan on hanging with Nicky Hayden in the corkscrew at Laguna Seca, you don't need to worry.
You might want to just adjust your suspension to your weight, and riding style. Set the sag to begin with, and then see how the bike feels. The thing to knowing how a bike feels is having the experience to know what it is doing, and what it should be doing.
I know what you are going through though. You just want to make sure that everything about your bike is perfect---It is! You have a 2003 R6, right? If you knew the millions of dollars that go into testing these bikes to ensure that they are awesome, you wouldn't worry so much.
Trust me, your bike is fine!! :mrgreen:
You can't screw your suspension up....unless you start yanking out springs, and whip out the hacksaw on the rear shock. If you want to play with the adjustments, write down where they are now, how many clicks out, and how many lines are showing. That way no matter how out of whack they might become, you can always put it back to where it was.
