+1 for the weight on the footpegs.
I've been doing this a lot alongside countersteering.
The idea being that when you're turning left, you push right to tip the bike while at the same time push down on your right footpeg. enough that you're actually taking a fair bit of your body weight.
This does 2 things. It shifts your body weight to the left and therefore inside the radius of the turn. It also focusses the point at which your body weight is acting on the bike low down on that right peg which keeps your centre of gravity low. The added bonus is that if your weight is down there, it's not being transferred through the bars so the front wheel can do it's thing unhindered and go from countersteering to turning in with the bike.
Make any sense?
Anyway, it works for me. Guess you have to try it. You're probably already doing it! I had a LOT of time to practice it on the track which was great.... except I strained EVERY muscle from the waist down!!
