If you sell it reverse the cylinder head covers.....they are on the wrong side. The left side one is on the right side and probably vice versa.
That sounds completely normal, and typical when loading it at low rpm. Consider than at 900 rpm you're getting only 15 rotations per second. The cylinder firing will be easily felt, as will the vibs as the clutch pads slip past each other, and this will vibrate the drive train with high amplitude movements. It is completely reasonable for the drive train to be rattling (loading and unloading) a bit.
And to Dons point, yes, if it does have a failing u-joint, this test could produce some rattle as the u-joint slop responds to the vibrations (even when lightly loaded).
Mr. dduelin may have spotted something important! If the cylinder head covers are on backwards and upside down, then there is NOTHING holding them down to the 3 contact points that they mount to!
The two front claws are suppose to be attached to the rubber grommets, and the rear grommet plugs onto a post, If they are loose, and mounted incorrectly like Mr. DD was kind enough to point out, then they may be rattling against something causing this noise.

Yes, you are right. Then there is nothing wrong with that bike.The covers are not on backwards, the video was shot upside down.
And to Dons point, yes, if it does have a failing u-joint, this test could produce some rattle as the u-joint slop responds to the vibrations (even when lightly loaded).
It sounds like my bike did when I bought it with 26k on it. I could feel a bit of a knock through the bars at idle, most pronounced with the clutch out in neutral but it was still there a bit with the clutch pulled in. Now with 111k miles on it it has gotten louder but still sounds about the same. I have had a few people ask me what is wrong with it...and I just reply "nothing". I think part of the reason we hear this sound so clearly is because our bikes are so quiet, even soft normal sounds seem loud.
