I had V & H Power Duels and Monster Rounds, FP3 and Arlen Nes Big Sucker breather installed on my 2015 RGS now I hear a whistling sound. What is that from?
Where do you hear it- near the heads or near the muffler joints? Does it change with speed or rpm?
Maybe what you're hearing is the sound of the new intake.
Check to see if all the fittings and clamps are tight.
