Hey. Just wondering if anyone can tell me what manuals are available here on SOHC for the CB550. Seems like there is the Honda Owners Manual, then there is also some more broken into sections, Engine, Electrical etc. When I download these sections, the files are named HSM0000***, so I assume maybe these are from the Haynes Service Manual. If anyone can shed some light on this, it would be much appreciated, so that I know which manuals I do and do not have. Cheers!
