I have a 2009 FX SHO cruiser. While riding the other day I realized if I hit the gas really hard and let off before the exhaust coming out of the water which usually drowns out the sound it almost sounds like there is a blowoff valve noise right in the engine compartment by the supercharger. Is this normal? I checked all of the clamps and everything is on tight I am just wondering if I am starting to have a supercharger problem?
