It dfinitely wasn't every bike that had this rattle, although I seem to recall once in a while others having a similar rattle. The rattle was the top part of the cover rubbing against the ICP, and it was LOUD. I mean a persistent BUZZ especially at buzzy 4k range, like someone with a Kazoo in my ear. At that point I'd never had the windscreen off, so it definitely wasn't anything I caused. It also didn't start until I would say after a couple thousand miles. There might be a thread or some post about it, I really don't remember any more. I know I posted a thread about hunting down rattles but that's been a couple years ago. I "fixed" it, or at least did a couple things to keep the rattle from happening, but the parts no longer on the bike now anyway.
I laugh when people tell me how good Kaw's fit and finish is these days. Found a pin head sized hole in my tanks paint. A perfectly straight scratch line in the muffler finish, extremely thin and barely noticable unless you're really looking if both sides had it I would've probably figured it was a process thing. Then a run in the finish on one of the passenger peg brackets.
