I had my busa tranny done by them and a few of my oil cooled GIXXERs as well,I'll tell you,there one of the best,You will feel the difference,Its a more solid shift,and won't jump out,well worth the money IMO,My tranny broke in my busa with only 1200 non raced miles...I also added the billet shift shafts..
