Put a helicoil in the fork.
Also, balance the wheel pant so that the CG is at the mounting hole.
It wasn't until Bill added weight to the front end of the pant that the nose wheel shimmy was eliminated on 39WG.  A tail mounted camera proved the theory.

Considering using a nylock nut to the machine screw to avoid replacing the fork or maybe having the fork filled in and re-tapped.  I have determined the most likely cause of my occasional shimmy is the fairing vibrating around because the screws back out.
