I think it is the drive bar. I have used a few of the bars on other machines and if they get a little loose they can rattle the sides of the tube.

If you can't fix it, I have an HM direct drive I would trade for it.

It says in the info to never run the machines unloaded. They defiantly run loud without a cart in it.

It could be the white plastic spacer on the bar fits really loose in the grip of the loud machine too.... try swaping the grip and or bar and see if it runs more quietly.

looks like the drive bar being slapped around like a 2 dolla hoe....making all that racket

A tiny loose rubber band may help with that, they have hooks on the side of the machine for the band.

Try backing your cam out (away from the motor a tiny little bit) and then tightening it,,, I'm pretty positive that's the issue. Lemme know if that worx.
