Im a vary new street rider, but when I road dirt bikes I sometimes got a wiggle vary similar. the only thing I ever found to correct the bike is to lean the bike as far over as I could and turn the bars with the lean. I know its not always possible but it might help some one. so from what I can decipher is that when I lean hard it forces the obtuse angle between forks and frame, which puts more G forces on the bike vs fork. I found this force is greater than what Is causing the wobble (obvesly wont work in all situations) please experts let me know what you think.
