You're sprocket or spindle could be bent or your chain alignment could be out of wack. Do you have any spacers on the drive side crank arm?

Bent sprocket is one possibility.

You could also have a stiff link. Wait, is your Fit TRL2 starting to have problems? OMG NO WAY. I NEVER THOUGHT THIS WOULD HAPPEN. But anyways, this could be the cause of a few things.

To fix the stiff link, move the chain back and forth like it's supposed to, and then wiggle it back and forth the way it's not supposed to.

It isn't your chain I guarantee it. I've seen 2 cases of this. Either you bent something or you are missing the sprocket adapter.
