I'm back to the point that I'm sliding off the seat a little now along with upper body lean and I've adopted that basic technique of not tucking down in the corners, sitting up high and concentrating on getting my upper body to the inside. I actually visually reference my head and shoulder position in relation to the mirrors using my peripheral vision and how my arms are bent as I take corners.
As I said, I am still having to consciously make myself do it because I don't get enough miles and/or seat time ( read as: not enough repetitions) to truly burn it into muscle memory. Maybe some day...
Do you have a link to some more information on the teqnique you use to work on your form? I have not heard of that.
I do know that I tend to tuck onto the bike as I go into a corner. Even though it feels ok I am sure I am far from doing it properly.
Sorry, no link... I just put stuff together over time from different books and magazines, as well as that pic series (or one like it from somewhere else a while back) that BusaFever posted. That and watching the Hell out of the fast boys in AMA and MotoGP and trying to analyze and understand their movements and why they would do certain things.
