Anyone know what this sound might be? Only happens on bigger hits / jump landings. This is my first ride after bumping my Fox 36 from 160mm to 170mm and I can’t tell if it’s the fork bottoming out or something loose up front (headset/stem/brakes). Video attached. Any ideas on what to check first?

He landed on a small duck.
You rear tire rubbed against your seat most likely
I think your behind hits the tyre
I don’t think it would be the fork bottoming out, maybe something related to the derailour?
That is either the breakfast burrito you ate on the way to the trail OR a tire rubbing something. Like your seat when you bottomed out.
Cabbage and broccoli
Sounds like You got a little B-hole buzz and I’m not talking about the pollinator.
That’s your bike saying go bigger wuss.
JK, likely seat on tire…. IF IT WAS ME, I would take ONLY the shock out. Leave tires and everythign else on the bike. Once the shock is removed then cycle the rear wheel up and down observing for contact points. I’d hate to see the tire buzzing on soft carbon. My Transition Spire lost a signifincant amount of frame in a siimilar fashion.
It’s the bottom of your left shoe hitting the back tire
Definitely Sasquatch mating call
Ahh the seat/tire thing makes total sense. I’m new to MTB and I actually messed up my dropper cable this morning, so I just slammed the seat down basically to the frame collar before going downhill to make up for the dropper not working. That’s probably what it is.
I’ll check the back of the seat for any rub marks (could even be my shoe rubbing too). First time riding flats so that’s also possible. I’ve bottomed out a fork before and it sounded different than this.

I can’t imagine he didn’t feel his ass slam into that tire😂
Check if your headset is properly installed. The two knocking noises makes me think it’s on compression and rebound of the fork that the headset is moving inside the head tube.
And as you said, you changed your fork setup so most likely area where something changed.
