Get used to handling the bike and your confidence should grow with your skill. Buy a good text, like Twist of the Wrist by Keith Code, and digest. Then get yourself to a track day/race school, and benefit from quality instruction. Then you'll have that knee down.
It's far more important to understand why a bike behaves in a certain way, and why it is good/bad to do certain things, than it is to get a knee down. With warm tryes, a clean dry surface and riding in circles with cheeks off seat you will get your knee down. If you are unaware of how a bike behaves under certain conditions, your arse will soon follow your knee onto the road surface.
Good luck, don't rush it, these bikes aren't cheap to fix. :Burned up:
