Agreed that the stator might be fine. I don't see any harm in just replacing the cover, replacing the oil, and seeing what happens.
Assuming the gasket's trashed, you'll need one of them, too, and you might want an extra, in case you screw up the first one. You'll need some gasket seal, too, for around the cable grommet.
That loose gear to the upper-right is the starter motor reduction gear. When you re-install the cover (or install the new one), make sure you don't knock that gear out of alignment. Trust me on this. The only plus to misaligning that gear is that diagnosing that problem takes only about 50ms when you try to start the bike.
