For some really god instructional videos on utube look up McRider the guy does professional instruction. I've learned a lot and turned my younger brother on to it helped him a lot. 

 

Learn countersteering and practice it. Try to keep your eyes level when cornering, so you don't get that, 'I'm falling' sensation. Look where you want to go and the bike will follow. 

Something I learned by "accident", if it's even a little wet, watch when you pull up to a stop with those big white painted arrows....they are slick. Some places mix sand or other anti-slip with the paint, many do not. Even then....I pulled up to a stop, put my foot down and almost lost the bike as my foot slipped.

I ride as if I am a target to every vehicle on the road, I'm not invisible, I'm a target. Thats just me.... and SLOW DOWN....
