Hello I have a slightly raked 69 CB750 (sandcast) 1000157/E1000199, after much reaearch on this site I can determine it has many period correct parts however the frame is modified forks, headlight and handlebars have been changed among other updates on this old school chopper. I’m looking for advice from the experts here if the bike is worth restoring due to the low production # or should i part it out and offer some of these rare parts for sale.  There’s alot more info i need to share but for now just curious which direction i should go.  Thanks in advance.
