What Sean said FTW!
The best advice I got from a female control rider (one built like me) was tits to the tank!! But this only works for tall women, or like myself, women built like spider monkeys!
My shorter friends dont have the reach of leg or arm and have to position differently. Find a CR built like yourself and ask her what she does.
I practice my form on the street too, just for fun, so that now, even when taking it easy on the street, I immediately fall into at least somewhat proper form for turns and such, just because its a comfort thing. It just takes practice. *hint* You can also do it going in a straight line to get a feel for it at speed...just saying.
