For sale here is the service - repair manual for the 1984-1986 Suzuki GSX1100 / GS1150 motorcycle. All information is factory material, in PDF format. The print is light, but very readable (due to the original print in the manual being very light). The manual is in English, and contains 306 pdf pages in total, maintenance schedule, component location, service and repair procedures, and much more.

The advantage of having the manual in PDF file format is that you can quickly jump to a specific section to find what you are looking for. Also, you can print out a section to take with you to to the shop, and make notes on them (you probably wouldn't write on the factory book manual).
