Seems very unusual for such a low mileage bike to have these problems. Maybe someone ran it with no oil or something. The old screw driver to the ear trick could help you pinpoint where the sound is coming from.
If the sound gets louder as the oil reaches operating temperature that'd point to possible wear in the big end bearings. Cam chain noise usually is the opposite and gets quieter as the oil heats up. A trick for checking big end bearings is to take out the plugs and rotate the piston to bottom dead center then push a screwdriver down on the piston and feel for movement or a slight clunk sound.
There's a video on youtube of a fazer with worn big end bearings. It's called FZS600 Fazer Engine Rattle. You could compare your noise to that one. Having said all that I think you should bring it to a bike mechanic and let them listen to it.
