Restore or Modify

www.bikeexif.com featured a bike today which started its life as a WWII Canadian military bike - James Roper-Caldbeck's beautiful XXX750-WLC.

This bike has come a long way from its original drab green.

This past week I spotted a Indian 741 in the local classifieds.

Should a bike like this be left in restored condition or modified as a piece of art? This is a touchy subject for vintage motorcycle enthusiasts.
