if your learning to wheelie you should not be practicing on 3rd.. Try second gear- bounce/compress & clutch the bike at the same time, it's like a rythem that you will get better at as you practice. The MOST important thing about a "wheelie" is throttle control. Try being as smooth as possible when turning that wrist, there will be no need for rear brake control, shifting, or changing sprokets if you have throttle control. However, it's always a good idea to learn the rear brake just in case. I can slow down to 55 m.p.h. (starting at 70) on a regular stand-up wheelie on front pegs without touching my rear brakes (stock 1000). When your smoother with the throttle with time, you will get braver and get it up higher until you "find" the balance point. Always wear your gear and practice where you can focus and not worry about cops and stuff.
