Thank you for viewing. I am offering a set of the popular CB750 (RC39) / CB750 (RC42) Service Manual, Supplement [N], and Parts List. The cover of this book has some age-related soiling and wear, but there are no noticeable stains or missing pages in the main text, so there are no problems using it for maintenance. (Although it is the RC39 manual, it is the base model, so the basic parts are the same as the RC42) It should be very helpful for procuring parts and maintaining your beloved motorcycle (Detailed information on inspection, adjustment, repair, replacement, removal, wiring diagrams, and troubleshooting is included), so how about it if you are looking for one? *Please consider this item as used and understand that it is non-returnable and non-refundable.
