I have this sound coming from what seems to be the front part of my bike. I just changed all the vacuum hoses with no avail. Everything is attached. My best guess is an exhaust leak.

Any help is greatly appreciated, the bike has made this whistle since purchased, and it's really bothering me so I figured I would make an attempt at fixing it.

INFO:
2001 Honda CBR F4i

Sound: High-pitch whistle/squeal

I'm not hearing anything on that file. Just silence, FYI.

 

Bike sounds perfect to me. I'd forget about it unless any other symptoms arise. You can spend a lot of time and money hunting for a little sound like that when it's actually nothing. Motorcycles tend to make that type of sound because most of them use a cam chain instead of a belt. If you're really bothered by it, I'd take it to any nearby motorcycle dealership and have one of the technicians come out and listen to the bike; that way, you can find out whether you're just hearing a normal noise or there's actually a problem.
