Not gonna sit here and tell you not to do wheelies. I'm assuming you're a grown man and can make your own decisions. With that disclaimer out of the way..
2nd gear is my favorite. Usually around 35/45, I'll clutch in, rev up (I don't look at the Rpms, I just listen and make sure the blip was aggressive), and dump the clutch. Bike comes up, and I usually just wait till I get high enough and then gently roll off. Usually I can just coast at BP with gentle blips of throttle. Back brake has saved me dozens of times when I bring it up to quick or too far back.
Biggest word of advice is gear up and get a cage, subframe brace, clip ons, and sturdy axle peg sliders. That, and practice slower. Don't chase. If you didn't get it high enough do not chase it out. Just bring it back down gently. Get familiar with that back brake and just try and find a lot, please.
