Lean more? why? if you can negate a turn at speed or faster with minimal lean angle, more power to you.

 

if you feel obliged to lean more, start but getting your *** off the side of the seat, holding onto the tank with your right knee, push your left knee forward along the the tank at first and then outward toward the ground. Once your puck touches, you know you're doing okay on the streets. If you lean further, you need to move you knee inward a bit so it doesn't scrape hard. It helps to have grip on the sides of your tank to keep your knee from slipping while you're hanging off.

practice this on wide open turns with no oncoming traffic and no obstacles along the side of the road in case of a get-off. Relaxed grip on the bars and if you're trail braking, be smooth.
