I'm just posting this so it will come up for others searching on this mod. I can't believe the difference it made! My Busa launches so much smoother now, under much better control. The only downside was that since I was able to apply so much more power...I had to deal with some tire spin, but my Shinko has about had it....so that might have been a factor. For anyone considering this mod...do it! I knocked 6/10's off my best time and there's more to come as I get accustomed to the new launch characteristics.
