Andrew, leaving aside the subjective opinions of whether the CB750 "deserves" this sort of treatment or not, I find your design aesthetics, artisan skills and innovative approaches both admirable and inspirational.
The last 33 pages of this build have been some of the most enjoyable I have come across on this forum and l look forward to the ongoing build leading up to the final product.
Personally, I don't think any mass produced, multi-flawed (by today's technical and engineering standards) 40+ year old motorcycle is all that sacred.
Having said that, I am also respectful of the people that pull off great restos, but at this point, give me a well done cafe'd or brat'd or chopper'd or trike'd or steampunk'd effort any day.
