Kevin, The holes that need to be oblonged are the holes in the gear mounting bracket (those that were drilled 7.9 mm on the building instructions). You will have to remove the seat(s), the R side panel and the seat mounting bracket. Jack the wheel up untill it is just touching the floor before removing the landing gear bolt. Have some one turn the landing gear leg while You run the drill bit through the landing gear and bracket mounting hole. This will oblong the bracket holes but not the gear leg. Stop twisting the landing gear leg when the wheel is tracking properly. The oblongation will be as little as a few thousandths to pehapes 1/16th inch. Make a shim to make the bracket hole round and replace the bolt.

I thought that's what you were talking about - thanks for clarifying!

How does one go about making a shim? It just seems the shim we’re talking about would be nearly impossible to make correctly or am I not envisioning something properly.Â
The way I picture this in my head the shims would likely be a tiny moon shaped sliver installed on the non-oblonged side of the hole (the side that the drill bit did not widen) between the nut head and bolt within the gear leg housing hole? Would the shims have to be the same thickness as the gear leg housing? I imagine you could cut/grind on a washer to make this or am I missing something? Does the curvature of the gear leg housing have to be matched?
