The exhaust (stock) on my Road King "chirps" like a bird when I'm sitting at a light just idling. It sounds like it's coming from where the mufflers connect to the head pipes, but it's hard to tell exactly. Chirping like a bird! Anybody have any ideas/fixes?

 

I've never heard of that one before. Maybe you should try buying a predatory bird or just a 12 guage.

 

Check the rubber bushings where the muffler bracket attaches to the rear.

 

That's exactly what I thought also when I had the "bird chirp" while stopped at Idle. Turns out it was a loose bolt on the head pipe brace / bracket just above the starter. Put some lock tight on the bolt, tightened it up and haven't heard a "peep" since.
it worked for me anyway

 

At all lights? What kind of road? Asphalt or concrete?

 

Sprayed the rubber bushings that my mufflers hang from, and, BINGO..........no more chirping! Thanks guys!

 

My Rineharts used to do that, sure glad they are gone.
