Now i think about it, I'm pretty sure it's just the crash bars that didn't fit. Had a lot of trouble getting sprockets for it which seemed odd, and the Haynes manual for the 600 isn't much good, but mostly i just don't buy parts because it's 50/50 whether it not they'll fit and i can't afford the risk.
Thanks for the help by the way, my shiny new stainless exhaust arrived today and after a few hours of hurting myself and swearing loudly it's all done and looks great
