To be honest with you, I used to power wheelie my busa until I learned how to slip the clutch. When you first try slipping the clutch, it may feel that the bike only wants to lundge foward. I had this problem until I kept practicing. It is a real fast motion on the clutch (with 1 finger) and romping a bit on the gas all kinda like one motion.
This is the only way I do it now. As far as the Busa, not really the right bike to do it on.
