SUZUKI GSF750 Service Manual. This is a GSF750, not a 1200. It contains information on the structure and maintenance of the oil-cooled engine. Suzuki's service manuals are easy to understand (I've looked at service manuals from various manufacturers). Even if you don't own this bike, it can be used as a reference book for those who are slightly interested in tinkering with machines, covering basic carburetor information, brake calipers, chain adjustment, overhaul of the telescopic front forks, and engine internal measurement methods. *This is my personal opinion.* To be honest, this manual was used on-site, so it's not in pristine, collector's condition. As shown in the images (8), some pages are dirty. Considering its age, it's still a relatively clean manual. There are no tears or cut-outs. Pure oil-cooled engines are becoming rare, so from that perspective, I think it will be interesting material. It's not sparkling clean, and there may be some oversights. I apologize, but please refrain from purchasing if you are overly concerned about the condition. Thank you for looking. Best regards.
