So I am out riding yesterday and I hear a high pitched whistle. I can only hear it when I am at a steady throttle and cruising, and as soon as I let off the throttle it goes away. It isn't loud, but it is present and I don't (knock on wood) have any problems with the bike. Is this a normal intake noise?
