ok, so i was out for a nice leasurely ride yesterday, and i noticed this high-pitched whistleing (sort of humming) noise coming from the engine. when throttling up, the noise gets louder and vice-versa. does anyone know what this freaking annoying noise is? i mean i can hear it over the pipes, which are LOUD! i was thinking it may be because the bike is relatively new with only 300 miles.

i don't know. any ideas how i can shut the noise off or is this just the nature of the beast?
