So the intake roar is quite pleasant on my '09 FE450 for a little while, then it becomes annoying as I am trying to commune with nature while I am blasting white-knuckled through the trees.
As an experment, I took a piece of perforated metal to use as a template, laid in on the underside of the seat where it would be above the air intake, and proceeded to drill a few hundred small holes (1/8"). I placed some tape around the drill to use as a depth stop so it wouldn't drill too far into the foam.
Results? It is quieter, a simple one beer fix. Now I can here myself screaming in my helmet as I wack the throttle.
