can anyone tell me if full givi luggage system from an fzs1000 fazer will fit onto a new 2008 fz1s fazer

um, it doesn't look like it, compare:

and

http://www.givi.co.uk/My-motorcycle/?ma=YAMAHA&mo=FZ1-1000-06--09

look at the pannier pdfs, they look quite different. The type of givi/kappa box they fit is also different.
