That 06 Busa is a Gen I. Mine is a Gen II. I'd hate to give any misinformation. I've changed my own oil, installed smog block off plates, changed the headers and pipes, extended the swingarm, lowered it and probably some other things. The worse steps are always removing the fairings! Lol! You can find the manual electronically here servicemanualsgsxr.com. I think I may have also found a link on the Extremebusa forum. Good luck!
