Hello , I have a kawasaki vn900c 2008 lehman trike from 2008, I have a shake in the handle bars at speeds over 52 mph and increasses at higher speeds . and yes i had the front tire replace and balanced, witch helped a little bit, and the foward pulley replaced witch also helped a little bit? but the shake is still their? Not a wobble... ? The shake is like a jake hammer. if that helps the tire is at 41 psi. Just wondering if anybody else had that problem and the cure?
