Nice bike mate, keep it original, I've seen some really poxy looking CB750F/F1 based "cafe" bikes, but not too many "originals", like yours!
CBJ, I'm not sure what your question is, but I've got K and F stuff here, I can try an F tank on my K frame for you, if that's what you want?
All the CB750F (and F1/F2/F3) tanks were the same as far as mounting points go, only difference (apart from badges, decals and color schemes) was the spiggot size for the petcocks, for some reason they went from a larger spiggot on the F/F1 to a smaller one on the F2/F3. I nearly fell over when I realised an XR80 petcock screws on to an F2 tank! Cheers, Terry.
