noise from brand new bike help

I've always noticed some clutch noise while idling with the clutch engaged (lever out) and never really worried about it.  However, last ride out on my FX I started to hear the same noise when riding on fire roads connecting trails, specifically when I would let off the gas and let the engine braking do it's thing.  I've never been able to hear the noise while riding before on previous YZ-F's, has anyone else noticed this while riding as well?

yes. 2016 yz450f. Sounds like bad bushing or bearings....but it's not

You're sure it's not the chain dragging on the top of the swing arm?

it makes the noise at a dead stop, on a stand, just sitting there at idle. Did it since the first day.

My question was directed to Cowboyona426, who stated his bike made noise while moving.  See the text I quoted?

I suppose it's possible, but it sounds exactly like the noise the clutch makes when idling in neutral.  I may pop the clutch cover off just to take a peek and make sure all is well in there.

mine makes it slightly at low rpm riding. From what I have heard from locals everybody knows what you are talking about. I'm not seeing metal of any sort in my oil, I'm changing every three hours with amsoil 0w-40 power sports 4 stroke synthetic. If it was anything I would have found something by now, I'm almost 20 hours in.

I was pondering this last night as my brain refused to shut down and go to sleep, I can remember a few times during the last ride hearing the sound I described while riding on fire roads, and it went away if I pulled in the clutch.

My new bike (450FX) makes the same noise. And for reference, my YZ250 2T made the same noise as well. I bought it brand new 11 years ago and it always made it. Right up until I removed the factory clutch and installed the rekluse, no more noise. I think it's just nature of the beast. I always wondered, and it used to bother me. But I got over it. Oil always looked decent and never saw any metal particles.

That 450FX has a lot of moving parts and it sure makes a lot of noises I'm not accustomed to.
