Mine does this at about 4300 RPM sounds like a hammer hitting the skid plate...I padded the plate for sound still does it...I'm over it 35,000 miles runs rides great...just sound bad at 80mph when I speed up it goes away;-)
What brand skid plate do you have ? Put 50,000 miles on my 13 without any sound like a hammer on my Yamaha skid plate, that same skid plate is now on my 18.
But yes I would say the 1200 Yamaha is generally a rattly sounding engine even though it ain’t going to fall apart.

I have an SW Motech skid plate but the engine noise was almost as loud even before I put it on. Sounds like a very noisy tappet but may be cam chain slap as Kmasa suggests. Probably just normal for that engine since others seem to hear the same thing.

Mine rattles a bit until I hit 3500 rpm. Then it purrs like a kitten. Mechanic thinks it is the clutch and thinks many bikes have the same noise.
