Motorcycle chain clatters loudly but only forwards?

The chain was taut and still in good condition; it was freshly greased a month ago. I rode it now after a week's break and noticed that the chain is loud. You can even hear it when pushing. When I push backwards, however, it doesn't make any noise. Could it be that it's simply rattling along one of those guides or grinders? I cleaned it, and now it's already turned quite black again.

Put the machine on the main stand and turn the rear wheel by hand.

Watch the chain race, swing the chain up and down, and then it's indifferent.

You can also measure the distance between always the same number of rivets with a sliding gauge, do this at different points of the chain, the mass must always be the same, they are not the same, the chain has reciprocated.

Lift the chain off the chainring once that's more than 4mm the chain is over.

Look into the links, if there are light grate attachments which place the O rings, then the chain links rub together.

My guess:

Unequal chain

What machine?

Is the chain tension right?
