Motorcycle control help?

Hey guys I just rode a motorcycle yesterday for the first time and it was a blast! However, it seems that I can't do two things. First, I can't make a quick abrupt turn going about 3-5 miles an hour, It's like a soon as I begin to take off, the sharp 90 degree turn is there. How do I accomplish that? Also, weaving the bike is a huge issue for me, I can do probably the first 2 cones, after that, I can't. Does anyone have any answers to these problems and any other advice to riding a motorcycle?
