Complete Supplementary Service Manual for the 1980-81 Suzuki SP400 / GN400 / DR400
Everything you need to know about each bike, including parts, layout, electrical, etc
Three separate PDF files for each bike, compressed to a ZIP file. Will need Adobe Acrobat Reader to view
SP400 is largest, since it focuses on the Engine that all the models use.
