I really enjoyed reading this thread as it progressed and even practiced some of the hand position suggestions in last weekend's race. I was somewhere close to 8 and 4, but moved them up to 9 and 3 to find a little more control of the kart. Needed a little extra input, I felt, but it was neat trying out the different positions for myself to see what all the talk was about them on this post.
One thing I'm curious about, since I'm taller than most, is my knees. The kart isn't long enough for me to get my legs all the way down, so my knees stick up and out a bit through corners. Should I be consciously trying to keep my knees tight against the fuel tank or can I let them flair out as I corner (as I have been doing)? There's not much more room for me as the kart already has an extended porch and the pedals are practically touching the frame.
