I actually have quite a collection of CB500/550 manuals going on, that I need to scan and share with the community here.

I have bought several on feeBay as well as having found a couple in new stock my business partner has picked up at swap meets
(for those of you not in the know, I am in the Automotive manual and literature business - see site link in my profile). I now have the OEM, Intertec (a couple different versions), Chiltons (2 versions), Clymer (like 4 different versions), Haynes (3 versions), and a couple of other manuals that cover many bikes but have SOHC Honda sections in them!
I have found with the Chiltons, Haynes, and Clymer manuals that the older versions can be MUCH better as they use actual photos and illustrations from Honda's manual, in them, to supplement their own illustrations. They all stopped doing this at some point in the late '70s and went to (often crappy) illustrations of their own - I think Honda must have finally told them to stop or something?

Also, there is a kewl version of the Clymer manual (fourth edition - 1977) that has a section titled "Exclusive high performance secrets from Yoshima racing service" in it that has various "hop-up" tech tricks, that isn't in any other printing of that manual.
Two-Tired - thanks for the links! I was aware of the former (I don't like how the manuals are broken up into so many sections, though, just like at that Italian site - I just want it one big, high quality .pdf!) and it looks like I have to register or something, for the latter?
