Run 2nd gear to ~7000-8000 RPM, then back off and re-apply throttle. This is a "power wheelie", I think it is easier and safer than the clutch dump method.
My SH is stock except for Helibars and it wheelies fairly easily, you shouldn't need performance mods.

 

Clutch wheelies are way safer than power wheelies. I suggest you get on a dirt bike or supermoto and practice if you can. The hawk will clutch up in second with about 2000 rpm above where ever you are. I like to clutch up about 4000 rpm by slipping it to 6000rpm. Once it is up, you need to roll off the throttle very little. This is what takes practice. It really is feel. There are guys who can clutch up goldwings. Our bikes are wheelie monsters and will do third gear clutch wheelies easily in the right hands. Power wheelies take longer to get in the air and you are in need of a gear change very early but they do feel cooler as you are on the power.

 

I know I can throttle up 2nd gear stand up wheelies and my brother says he bounces 3rd gear stand up wheelies at highway speeds really easy. I haven't really tried 2nd gear sit down wheelies.
