Hello everyone,
I just wanted to say thank you for all of the information on this forum.  I have an 06 GS500F and with all of the info you guys have posted, I have added the K&N lunchbox, rejetted to 147.5/65/22.5, and a Yoshi bolt-on can.  The setup is perfect and the bike is definately what I wanted now.  Thanks again.

I did these same mods last season too. Unfortunately I used a jet kit and my bike isn't running quite right. have fun with your new high performance gs 

sounds nice.  any cosmetics???

I haven't really started with any cosmetics.  I did the fenderectomy and removed most of the stickers though.  Looks alot better.
