The engine otherwise sounds great with a good deep throttle, but there is a constant noise that sounds like a whine or a wizzing that increases pitch when reved. It isn't overpowering and doesn't sound like its systematic of a problem, but to my untrained ear it jumps out at me. Is this typical of Hondas and particularly this make/ model? I hear the same sound in a lot of (but not all) youtube videos. Thanks!
