CarlSalter.com is a good source for downloading manuals, that should have the Suzuki Workshop Manual and some other bits on it. The Haynes Manual is also useful there is a download for that somewhere but I can't find it right now.
I use both. The Haynes in dead tree format in the garage and the Suzuki version on the computer. They are written differently so each have their advantages and disadvantages. I recommend both.
