I am trying to align the chain guard on my early C Shadow. It has straight seat stays and the guard is fouling the heads of the nut and bolt. Even if I was to use thin nuts and grinding the head of the bolt there would not be enough clearance. I am contemplating taking the easy way out and fitting a short spacer to fasten the rear of the guard to the lifting handle. The RFM has been check for trueness and may be out by 30-40 thou. The previous owner just pulled it in tight as the dents in the guard attest. Any ideas out there?
