After many requests I have finally added service manuals to the site, there is the official Suzuki manual (46.4MB)
covering all the slingshots, then there is also the Haynes manual (40.2MB) which also covers the GSX-R1100.

Right click on the cover and select "save link as", they are in pdf format so you need adobe reader to open them*
