Knocking sound

Parked my bike in a mall parking lot today and turned it back on to switch parking spots and noticed this loud knocking sound:

Can anyone give me some advise or suggestions before I start looking around the head?

Thanks!

I had the exact same symptom. Eventually the valve dropped @ 3800 miles for a 2018.

Thanks guys! I'm going to check my valve clearances and inspect my cams tomorrow. I'll keep you updated...

Valve clearances looked ok. Pulled the plugs and one of the tips came out into the cylinder. Used an inspection camera with magnetic tip on it and was able to fish it out luckily. Cylinder walls didn't have any noticeable damage so I put the bike back together and did a test ride yesterday. So far no more issues.

Thanks for everyones help!
