Chugging noise - is it normal?
Hallo, I'm in need of some advice!
Since I owned my FLHT, I noticed a strange (for me) noise from engine - it is like chugging or breathing and is noticeable from carb side. When I switch off the engine, there are some long chugs or "uffff" noise. Listen the video, there it is.
No any noticeable influence to engine output, no blowing somewhere outside heads, no oil consuption, no leaks. Heard it with injector and now after swapping hear with carb the same noise. 3 years still. Just curious, is it decides normal?

Bike has 70k miles on, done some top end works - piston rings, base and head gaskets, valves grinding.

Yes, the bike has free-flow K&N air cleaner, Vance&Hines exhaust, but the cam is stock

The stock air cleaner that all Harleys come with when new is actually a silencer, so any change of air filter body will increase induction noise. I bought my 1990 Glide new and was surprised how noisy it was after I changed air filter.

Mine sounds very similar. As mentioned it's a big air pump and you are hearing air being drawn in after you shut the engine off. Nice bike.
