I have an chirp on my Fatboy at idle and pulling away in 1st gear. I installed Bub Jug Huggers on the bike, thinking it was the Pythons that were on when I bought the bike. I took the bike to Harley, and they have no clue. First they said it was just they way they are. Wrong. Then they said it was the baffles. Wrong. I took the baffles out of the Pythons and it still chirped. Next he said try the gaskets at the heads. Maybe. I'm not sure about the one. I used the gaskets that came with the Jug Huggers. Thoughts?
