Nearly all of my shimmy problem was solved by simply balancing the pant/wheel fairings. I also reduced tire press. to 22 pounds. Bench testing revealed considerable aft weight prior to balancing.

The wheel pants need to be s tatically balanced fore and aft. First remove the wheel pants and build a j ig that will freely support the fairing along the axle center line first. T he rear of the pant should be considerably heavier. Then add weight to the very front of the fairing until it balances. You can add the weight to the outside, then when they balance, epoxy the weight inside to the front of th e fairing. Lead shot and epoxy work great for this.
