Ball of your feet on the pegs. Coming into a turn shift your butt inside, weight the inside peg with the ball of your foot, and counter steer into the turn. At apex begin weighting the outside peg to stand the bike up and get weight out side then accellerate til you see god...or your next brake marker..whichever comes first.
I have found that when I am really trying, I almost never have much weight on the seat (except for straights). Weighting your pegs to turn, plus counter steering make a world of difference. Watch you don't actually turn in to much and run off the inside...thats how much difference it makes.
