I have been a dirtbike trail rider for almost ten years. I just started into quads and have logged 4hrs on my 450xc, and just recently started riding on a broken down, unmaintained race track. I got enough guts to start jumping and have tweaked a couple things like, thottle on the launch, and its been getting better. But on my really good launches, when I am up in the air I feel my bike pull ahead of me and my boots slide back from the pegs until they hit the heel guards on the nerf bars. So any Ideas on what I am doing wrong?
