A fellow on the KTMSMT forum has spent a year making one hell of a resource manual for the SM/SMT bikes. It is a free 400+ page.pdf down load, and is one hell of a publication. Anyone with one of these 990's can benefit from his experience and efforts. See the first post in this thread in the Orange Crush forum for the link. http://advrider.com/forums/showthread.php?t=845657 Many, many thanks to Kevxtx!
