just installed back oem header pipes with se slip on mufflers on my 08 fatboy.had short shots on the bike when i bought it so i realley was never able to here the engine much. at idle, is it normal to here some ticking noises coming from the upper end ? seems a little more at the front cylinder. if you go just above an idle it goes away, bike has 13000 miles on it and i run mobil-1 20/50. my first harley so im learning alot has i go. thanks everbody for all your input.
