Try this link, for download or for sale. Suzuki dealers can order them but they are often expensive if they say it may take six weeks. They have been known to source their own manuals from OEM partslist sellers who have remaining copies.

The following 2 links provide threads to these OEM sellers and have normal on-line shops. Cheers.
