I've got an early 2009 F800GS that was purchased in October of 2008. This was roughly the 800th bike off the assembly line, if I'm reading the VIN correctly.
Multimeter reads 14.07 volts at idle and 13.88 at 3000 RPM.
This seems in line with what Joel reported at the beginning of this thread.
I'm starting to think there was an in-line change to the OEM regulator made sometime in the past several years; it looks like the newer bikes are consistantly putting out slightly higher voltages.
