If the break-in oil was changed at 500-600 miles like it's supposed to be, I wouldn't worry about the oil. The only "special" tools required to work on these bikes involve engine repairs and fork and triple tree repair/adjustment, neither of which should be a concern for a loooong time. Everything on these bikes is metric, with the exception of a few Torx screws (with metric threads)which can be replaced with regular metric bolts or allen heads and the security Torx which hold the tank badges on. If the brake fluid looks clear with no goobers floating in it and the level is correct, don't worry about it. If it is cloudy and goobery, change it.
Otherwise, as mentioned, replace the gas, drain the float bowls, add a little Seafoam, check for vermin in the voids, then ride the thing and enjoy. Any hiccups or burps, report back and you'll get lots of guidance from the cognoscente...
