The most important advice I could offer, is "situational awareness"! Which covers dozens of factors like condition of the pavement, condition of the tires and equipment. Pryor knowledge of the road and the surroundings, side roads, turnouts, mail boxes, traffic, etc. The best way that I can tell you how to find your speed is to: approaching the corner, Turn your head and eyes, to look through (as far as you can see) the corner, move over in the saddle towards the inside of the corner, Be SMOOTH as possible, downshift (engine braking). Toes on the pegs, apply front brake (Only) all the way to the apex if necessary. Drag pegs thought the corner, roll on the gas at the exit. In your helmet, yell "Yee Haw" and look for the next corner!

Find a series of corners that you can practice on to develop the "feel" for the amount of lean you have in the corners. You can use you toe as a feeler in the beginning. With your toe on the peg, as you are thinking you are at max lean, try to touch the pavement with your toe. It will teach you that you can lean the bike over a lot further even after the pegs have touched down. In the flat land, you can get on an interstate clover leaf and spend the day making right hand turns and never leave the clover leaf.
