I looked at what I have and I also am missing from page 10-8 to 11-9??
I went back to the original post in the Download Motorcycle Manuals thread and looked for a K8 manual. I don't see a particular manual for the K8 F3 (that's what it says on the cover of mine) nor do I see the link that you listed. The one I have has 213 pages (less the transmission section as you noted).
There is a manual that is listed a couple times as:
Complete CB750K0-K8 CB750F1-F3 1969-1978 Shop Service Manual:
