The swing arm is off 2000 XR 600r disc brake model which has alloy linkages. Had to machine outside of steel stepped bushes on pivot down to about 2mm then grind inner hardened sleeve to a few thou wider than finished pivot.
Loosened rear eng mount bolts & jack frame apart to slide in. One of the eng mount bolts is spaced with a washer.
Could not use outer seals so fitted large 'O' rings & keep it well greased.
Ground off brake caliper mounts then had a mate fabricate and Tig a lug to locate original rear wheel with a wider spacer on left side.
Used the XR 600 alloy lower link as it fits 82 Xr 200 frame. Had to cut ends off then fabricate new link to be 13mm offset & 98mm long. Make sure grease nipple orientation is correct.
Used original 200 shock which fits 600 linkages perfectly.
Didn't have to cut or modify frame to fit.
I will be at Bulahdelah Vinduro if anyone wants to check it out.
Cheers Woodsy
