I'm considering getting an FS650 and then convert it for offroad use (as there are more used FS than FE available). As far as I have understood the shock length is 21mm shorter on the FS, does anyone know how this is done and how it can be modified so that it gets the same as the FE? As for the fork it seems like there are only more spacers to increase preload so I assume it's fairly easy to modify.
