I've been treating this subject like I treat wheelies; that I'll never have the balls to do it for more than 1/10th of a second, but those guys make it look SO easy. So I keep thinking I stand a chance.
From what I can figure, you either use engine braking or the rear brake to get the rear out, and then keep it out through he corner by using the gas. BUT, the transition from the back tire spinning slower than the front, to spinning faster than the front makes me think of a nasty high-side.
I might not even be close, but I just wanted you guys to know that I have at least put some thought into it. For what that's worth.
