The buzzing noise happens when high RPM goes back down to Idle. This is a new noise I haven't heard it before.

Re: Strange noise
I dunno sounds like that exhaust bolt is tight but not tight on bracket and seems to shutter to the sound on video to me. For shits an giggles check that. If you look at the video Im talking about the expansion pipe at the kicker bracket. If you notice it seems loose in a sense. The kdx loves to rattle bolts loose it prefers mud Loctite
If you cant fix it with a hammer, you have an electrical problem.

Re: Strange noise
sounds like loose pipe bolts to me. for me, I loctite blue everything. every 2t I've had likes to back bolts out, even the bolts that hold plastic on the bike, and it never happens in the garage or backyard during testing, it's always on the trail.

Re: Strange noise
maybe this is because I never see my pipe when im on the bike but doesn't it seem to vibrate more then it should ?
(look at the rubber mount doohickey and you'll see)
im sure they do vibrate because all those doohickeys on both my bikes are broken but it seems excessive to me...I agree on the loose exhaust/bolt

Mine sounded like that after an enduro.It turned out to be a motor mount up front.The nut was gone.
