VIBRATION - deciding too much; and living with it.

[Hedge_imp]

I'm gonna thrown in my 2 cents from my experience with my 450 mile 2014. First, to me there is a huge difference between a buzz which I hear on my bike and a vibration, which in my world would mean shaking of some sort. That said, I hear a buzz from (somewhere unknown to me as of now) between RPM 3400 and flattens right out at RPM 4100. After 4100 RPM and below RPM 3400 it is virtually quiet. It is also vibration-less at all RPM's. Not sure where to begin my investigation for the buzzing, but since others have said that simply changing the oil to another brand or weight has worked for them, I might start there. Note, it isn't really annoying but like any eye-sore, once you see it \ hear it you just can't get away from it!
