With my "Romper Room Magic Mirror", I can see a lot of goodies on that XR. Did it come with any spares? There should be a decal on the frame for racing, usually seen where the VIN is located on the steering neck.

Welcome from Melbourne, Australia. What a great find! You have saved yourself a LOT of scouring round on the net and various sources for those very tasty aftermarket bits your bike already has, plus a racing pedigree. Great score.What did it set you back?
