Yeah, that's exactly what I'm talking about. It doesn't bother me at all, just was wondering what causes it. I think it feels cool, it could put me to sleep if I started counting resonations!

(It sounds almost exactly like a twin-engine airplane with the props slightly out of synch.) When my bike was new, it would do it around 3.5K RPM pretty consistently. It had completely vanished until I noticed it last week, but only for a brief period.
I don't think it is serious, but it is weird. I suspect it is some strange vibration resonance where the frame or some component of the bike resonates with the engine vibration.
