Weird noise on shut off... 2018 Fatboy 114

Hi guys. Has anyone experience anything like this before? Took about an hours ride, fairly spirited so the bike got warm. Got home and noticed this odd noise when I shut the bike off. The issue repeats currently, but may be different when cold?

Not sure if attached video works?

I've heard that before on my '20 Heritage, but I can't remember if the bike was warm or cold when I shut it down.

Your idle seems kind of high to me. Is that normal?

thanks Hulkss, that makes sense. Haven’t heard it before, so I got a little concerned.

2019 sport glide. Yes I get that about 20% of the time. I never worried about it. My idle tends to be high too which is my biggest gripe about this bike.
