Need diagnosis and advice.

So I've been riding some rough single track the past few weekends. On a couple of the really steep rocky hills when I was losing my momentum I would hear what seemed like cam chain noise, sometimes a solid knock when I killed it. That concerned me but after cooling down again the bike seemed fine.
What concerns me now is while unloading after my adventure yesterday I noticed a tick or knock noise while pushing the bike in neutral.
Btw it's a 2014 stock except for air mixture screw. 490 miles with oil changes at 75 miles and 250.
Anyways listen to this video and see what you think. Thanks in advance.

The fast clicking is normal the slow clicking is not. Look in from the back to see if a rock or something got caught near or on your front sprocket.

Thanks twrog. Yeah the bike is up so I could look for a rock in there unfortunately there wasn't.

Do I take it to the stealership and fight for the warranty to cover it?

It sounds like something chain related. Is your chain properly adjusted and lubed?

If you still have the rear wheel safely supported off the ground, try starting the engine in neutral and use the rear brake to keep the rear wheel from turning. Any noise?

Now release the rear brake. Your rear wheel should start turning. Any noise?

Now put the tranny into first gear and release the clutch. The rear wheel should start turning. What do you hear?

[one4fishing]

Pretty sure the noise is coming out of the gear box. But out of hopes its not ill jack it up again and try it.

Well I thought you were on to something Brian, maybe you are. The all to familiar " is the chain properly adjusted and lubed?"
I scoffed at first, then checked. Well I was off by one click on the snails.
Feeling happy that might be it and I was an idiot I quickly readjusted and jacked it up again. Same noise.
Started the bike put it in gear and let the wheel spin can't really hear it. But when I brake and slow the motor down you can feel it clunking.

You think being out one click could have done this?

[Devils Advocate]

Could have. The front sprocket is on a spline shaft and there is a little bit of play within the groove that holds the sprocket with the keeper on. It will slap back and forth within that groove. You may also want to take a long nosed oil can and try and get some oil between the sprocket and shaft.

That makes sense. one can see something inducing unusual vibrations in the visible portion of the chain itself, likely from the front sprocket.
