Power wheelies are fun and all, but to be honest...clutching should really be your goal. It is the most controlled and effective way. If you use the clutch you don't have to match your rpms with gear and road speed and all that mess. The nicest thing is yo can do nice controlled slower wheelie. I agree with some of the comments made tho too. Buells have mountains of torque right where you ride, so actually riding them takes more finesse than a high reving 4 cyl that is much smoother at cruse rpms.
Try taking off slow from a light, just letting out the clutch a little till you're around 10-15, then mixing a little more throttle and clutch feed. Start slow and get increasingly aggressive with it. Careful though, there is way more that enough power to completely flip the bike faster than you can blink. Once you got this down, just translate it into second gear.
