Vibration noise ar high RPM

For about a week a was getting a noise that sounded like the fairing vibrating around the headlight every time I had gone above 8,000 rpm. It would get so loud sometimes my mind would make the noise louder than the exhaust. Well, I tightened-loosened-tightened every allen bolt and it still was making the noise. inspected around the radiator area a dozen times and no luck. However, I didn't touch the under cowl because I swear it was coming from the head light area. Yesterday a small leaf was stuck to the underside of the bike and when I pulled it off I saw the under cowl move. When I changed the oil 900 miles ago I must have not tightened the highlighted bolt in the picture because it was 2 complete turns of the wrench loose. Took the bike for a ride and no more noise. I knew there was nothing wrong with the bike the whole time because it wasn't a sound that an engine and transmission makes but it did get kind of frustrating not being able to locate what part of the fairing was loose.

I get it too, haven't been able to identify it. I'll take a look when I get home!

My oil hasn't been changed yet, but perhaps the dealer forgot to tighten it? Weird so many people are getting the same rattle. Wonder if the bolt/hole has some defect...
Unfortunately, I did the oil change myself so it would be my fault if anybodies but I found if the holes aren't lined up perfectly when tightening the bolt it binds up and it is easy to mistake that it is tight because it feels snug but then if you shift the undercowl a little with your hand and it lines up the holes and you can tighten the bolt down the rest of the way.
