well, as much as I am against doing wheelies I am going to give you some advice. You sound like you are new to riding, if you MUST do wheelies, don't do them in first gear, it pops up to fast and too hard. Get into second gear at about 7-8k and blip the throttle (quick short twist and let off) to compress the front suspension, then lift slightly on the bars and go full throttle. This all has to happen very quickly. Or you can "clutch it up" I'll let someone else explain that.
The best thing to do though is not wheelie, but that's your deal.....(SEE everyone, I'm being more civil with the people that I don't agree with, I'm getting BETTER!)
