Curious how loud your blowers are when your sitting on the bike fully warmed up. Another I saw locally makes ZERO noise at idle unless you put your ear up to the intake. He wasn't much help since he had no idea what filter was in it so I wasn't sure if it was stock. Anyhow I notice on mine if I'm sitting on it at a light I can hear the blower similiar to what I hear if I put my ear against the duct up front. I mostly hear it at idle, after that with the Brock's exhaust I can't hear anything else. But it sounds metaliicy if that makes sense. I'm assuming it's normal?
