Welcome to the club!!!
You just had one of the most knoledgeble minds on this forum give you some great tips! Thrstrmech knows what's what when it comes to Buell knowledge!
This forum has a great knowledge base!
One thing I'm sure you've probably already noticed about your Buell is the fact that it will NEVER match the straight line speed of your GSXR. That being said, one of the most cost effective "performance" mods you can do to your bike is to insure the suspension is properly set up for your weight and riding style. The link thrstrmech posted should also contain a downloadable owners manual, if you don't have one.
What a Buell will do, that I don't believe many bike on the market can duplicate, is rail curves! It's what got me addicted!
