I have a copy of the Busa Factory Service Manual in PDF format. I have put it in my shared files on Kazaa. It is under Hayabusa Factory Service Manual. It is the only one I have seen listed on Kazaa. I don't have enough web space to host it. If you want it, you can download it from me. I leave my computer on most of the time. My Kazaa ID is cbriggs3.
