Beautiful work. Nothing like a frame up restoration. The frame, triples, and CR500 USD forks all look awesome. The XR600 shock was also a good find. This will end up being better suspended and lighter than a new XR650L and still be air cooled. Very cool.
Keep it light.
I hope you use a lithium battery and other light bits ... this bike deserves it!!
