I checked for the crack and it is just a mark in the dirt.  The other vibrating part is a rubber motor mount I believe.  I'm starting to think it may be heat shields but I have tried to hold them in place and the rattle is still there.

Hello.  I have a 2023 cforce 600 touring with 500 kms on it. It has developed a very bad rattle while idling.  At first I thought it was the sliders on the primary rattling but now I think it may be something else. It started out small and grew worse over time, also noticed if I put tension on the wheels it almost stops. I have attached a video, any help in diagnosing this would be great.
