Ntodda, there's a nice description of suspension set up on Sportrider.com (
http://www.sportrider.com/tech/146_0006_susp). There's also a section about recommended suspension settings for different bikes tested by Sport Rider (
http://www.sportrider.com/bikes/146_susp_settings/) but they're not specific for rider weight.
I agree completely with drezx6r: Change one thing at a time, and keep a record of EXACTLY what you've done each time (date, which setting, how you changed it, what it did to your handling, etc..You might also want to keep track of how much gas was in the bike, since a full tank may handle a bit differnt than an empty one) After a few adjustments, you'll see a pattern emerging that suggests which further changes could be beneficial, and which could be detrimental. Hope this helps.
Keep the g's on!
