Still trying to track down a bad shimmy in the front end. I measured the outside rim on all four tires on the same hub and may have found the problem. First wheel was .030", second .065", third .110" and fourth .090". The last three seem awfully high to me, could this be my source of shimmy? I put the best two up front and had them both balanced and that helped but the shimmy is still there. How much runout should I expect from used wheels and how much from a set of new wheels such as some Magnum 500s or Torque Thrust II?
