Exclamation [Video] Squeaking/Chirping from motor, input needed

So I have an 06 street bob, motor has been pumped up, cammed 103, and I have this squeaking and chirping coming from either the heads or air cleaner and fainlty from the exhaust pipe. no it is not the exhaust pipe or heat shields. Would it be from the lifters or roller rockers? I have a video below, let me know what you guys think

Honestly, I can't hear the sound that is troubling you. Maybe a better tuned ear than mine will have an answer.

Make a post in the tech engine section of the forums and you'll get more concrete answers, but I don't think it's anything to worry about.

Sounds like an intake or exhaust leak.
I like your pipe.

It seemed the loudest at the rear exhaust. What cam?
I've noticed late closing cams make a chirp/squeek with certain exhaust.
Nothing to worry about. If thats what it is.

So I had some time earlier today to tinker with it. Pulled the AC off, butterfly isnt loose, exhaust brackets tight, top motor mount tight, header bolts... loose! After that there was a significant drop in the chirp, but still there, now it just sounds like it has a cam... right on! Now I can ride in peace.

I've done research and it might be a lifter? But these are brand new Fueling race lifters, oil pressure is holding nicely.
