here's a good article from the famous lance keigwin

"Please, tell me how to get my knee down."_ I’ve heard it a hundred times._ As a veteran instructor with STAR Motorcycle School, and a track day organizer who’s put on many dozens of track events and novice schools over the last several years, I talk with a lot of riders._ Questions from riders are pretty varied._ But the most common questions are certainly about riding position, weight shifting, and how to scrape knee pucks.
_

Let’s start by asking what’s wrong with just sitting on the bike, centered across the seat and tank?_ Well, the answer depends on how fast you intend to corner._ The fundamental notion of "hanging off" is that it allows you to keep the bike more upright, and that in turn provides a better tire contact patch._ A better contact patch means better grip through corners and under acceleration._ So it follows that with two riders traveling the same speed through the same corner on the same line, the rider who is centered on the bike has to lean the bike farther than the one hanging his weight off the bike._ And the "centered" rider will have more difficulty managing the drive out of the corner because of his more severe lean angle and less desirable contact patch.
Okay, let’s say you’re convinced that using your weight when cornering is wise._ Where do you begin?
Let’s break it down:
_

Balls of feet on the foot pegs
Riding with the balls of your feet on the foot pegs, not the arches, is best way to "suspend" your weight and make it easier and smoother to shift your position on the bike._ Move them to shift, of course, or apply the rear brake, but get them back into position and get used to it!_ If this isn’t perfectly clear, try standing up and then squatting on the ground._ See what you naturally do with your feet to stay balanced?_ That is what you want to mimic.
_

Swivel around the tank

Contrary to what a lot of beginners think, the movement of the lower body (legs and buttocks) is not a shift off the seat and away from the bike but rather a rotation around the tank._ It’s a swivel._ (This does not necessarily get your knee much closer to the ground -- let’s save that for later)._ Instead, focus on rotating hips and legs so that the forward leg corresponds to the turn direction._ I.e., when setting up for a left corner, the left leg and knee are forward on the tank; the right inner thigh is pressed firmly against the right rear of the tank.
__


Lead with the shoulder
"Point the way" with the left shoulder for a left turn. Right shoulder for a right turn. Remember the rotation!
_

Head and chest position

Where’s most of your body weight?_ From the waist up, right?_ So use that body weight to your advantage._ Your head and chest should not be centered over the tank._ Position your head over your wrist._ If you had mirrors, you would be trying to kiss the mirror!
Keep elbows down and tucked in
This is not flat track._ Your elbows should be tucked in and kept low, with forearms parallel to the ground._ This will help you stay relaxed on the bike -- it is harder to death-grip the handlebars and be stiff in the arms and shoulders._ It will promote weight forward and chest down._ And it positions your arms for the easiest and most effective steering input (nearly perpendicular to the angle of the forks)._ In a left corner you may find that your left elbow touches the tank or upper fairing, and your right elbow rests on the tank corner or even your thigh near the knee.
Look through the corner

Sure, everyone knows about target fixation and its danger._ But it’s only dangerous if you’re looking where you don’t want to go!_ Find reference points to focus on to help you drive through the corner, and ones to aim for on the exits._ Keep your eyes up, looking down the track and through the corners._ This will also help you build confidence in speed, as everything slows down when you look farther out.
_

Be smooth and use anchor points

The bike is happiest without you on it._ You force it to do unnatural things and fight its impulse for self-correction._ One of toughest things for a bike to manage is jerky movement, whether it’s your braking and downshifting or your body weight moving or bouncing around._ So, as you smoothly reposition your weight on the bike for an upcoming corner, use anchor points to "become one with the bike"._ That way suspension is handling one weight, not the bike doing one thing and you doing another._ Use your "outside" heel (right heel in our example) on the foot peg heel guard, and press your outside thigh against tank._ These anchor points are also useful to help turn the bike with your strong leg muscles._ Stabilize your upper weight over the tank._ Do NOT strangle the clip-ons._ As you practice these techniques with the bike on a bike stand, see if you can let go of the handlebars while in your cornering position._ If you cannot, then you’re using the clip-ons for support and that’s bad._ Instead, use your stomach, back and leg muscles to support your weight.__ Have someone press on your back so you can feel the muscles you need to use to resist.
Stick that knee out
So, how about that knee?_ Well the truth is, if you want to use your knee as a gauge to measure lean angle, you have to stick it out._ I mean, STICK IT OUT!_ Try this: stand up and imagine you’re facing 12 o’clock._
Lift your left heel high, leaving your toes on the ground._ Pivot your left leg on the ball of your foot so that your knee is pointing to 9 o’clock._ That’s what you want._ Can’t do it, or can’t do it in your leathers?_ Then you’re going to have to limber up or fix those leathers._ In time, as your speed and lean angle increase, you will touch your knee down with much less effort._ But the best way to get started is to exaggerate your motions._ It is almost always the case that riders feel they’re leaning or hanging off far more than they really are._ When they see pictures of themselves they often say, "Oh he caught me when I wasn’t practicing."
_

There are obviously more techniques to use to help you steer, lean, and apply muscles and weight to improve cornering speed and skill (weighting foot pegs, counter-steering, throttle and brake control, among them)._ But practice the basics first and get them right._ Remember, practice doesn’t make perfect, it makes permanent._ Learn to do it right early!

superbike UK magazine last month included a DVD that teaches you how to get yer knee down, as well as burnouts and stoppies.

performance bikes UK magazine this month has a really good article on how they taught their noob staffer to get his knee down in one day. this guy had literally JUST gotten out of the brit equivalent of MSF.
