Looking through the turn is the best advice someone can give; look even farther through the turn than you think you should. It seems intuitive to look in front of you or at the tire, but do not do that, it will cause you to turn wide.
The other thing to do is to slide you butt to th opposite side of the bike and put a little more weight on the pegs than you normally would - lean a bit on the inside peg more than the outside peg.
