2003 1600 classic.has anyone had this problem? if you let go of the bars the front end starts to wobble back & forth and progressively gets worse to the point of wrecking the bike if you don't stop it.I have had several shops look at it. balancing ,balance beads ,check run out , new tire ect. any ideas I'm beginning to take this personal. And yes I know your not supost to let go of the bars.
