At the TRack Day all my runs I had vibration at 95+mph. It would always and only do it once I got into 4th. It didn't pull to one side or the other. The only thing I changed was switched from my el cheapo kumho metric skinnies to M/T sportman fronts. I have a alum driveshaft so I know some people have had vibration with stock driveshaft. The only thing I can think of if I recently changed my brake pads and when I did it pushed the calipers out toward the rim so I had to grind a little more of the top of the caliper to avoid rubbing. I tested it the day before and didn't hear any grinding. Anybody got any ideas?
Thanks. -Mark

 

Rebalance the skinnies,turn them 180 first?Just a thought.
