That's not your switch gear, that's the throttle housing. Not sure what the holes are, but I'm positive they have nothing to do with the electrical system. I don't even remember them ever being on mine. Maybe someone's cruise control experiment?
Just following up on this. Tracked myself down a replacement throttle housing on the online auction site. Delivered today. Has the same holes, as does this bike I saw advertised online! So I guess they're supposed to be there for something!
