    First Busa And Could Use Some Advice.

    Love the site and this is my first post. I got my hands on a 03 busa about 5 moths ago and have leaned and done a lot on my own but any advice would greatly be accepted. I've done a full tune up/ fresh plugs , oil, tires , k&n filter , yoshi rs3 that I cut down to 12" and gutted the baffles...
