WTF is this sound after shutting down my Twin Cam?
What is this strange "whistle-like" sound that happens after turning off the bike?

I must be deaf. I didn't hear any whistling sound.

Are you talking about a little squeak (my thoughts) right after shut down that lasts a second or so?
Vacuum leak ???
For S&G take the gas cap off and see if it's any louder.
Just throwing S to see if it sticks.
Is the noise coming through the speakers ?

I can here a very slight squeek.
Kinda sorta like a fuel shut off.
Is that a California bike? with some extra pollution control stuff?

Yes, it's a tiny squeak at the very end of the video. It seems MUCH louder in person.
No pollution gizmos and the radio was off.
A "piston quiefe" !? LOL that made me laugh, but it makes sense.

If that is what it is there are several older threads on the TC's exhaleing a bit when shut down. It is a "they all do that" thing. Most noticable if you have a free breathing/exposed air filter.
