Do you have any other experiences to compare your findings with ?
With 'just' a single balance shaft, the engine was meant to NOT be as smooth as it can be.
On the other hand one can tell it is not an unbalanced inline 4 motor.
Vibration is an XS650 anywhere above 5K rpm, or a CB350 at highway speeds. Now those things will rattle the most insensitive hands (every time I pine for the good ole days, I just remind myself of those 2 bikes, in particular).
If your vibration really is out of the ordinary, it could be that your balance shaft needs to be tuned, but I would guess that it came from the factory properly adjusted and snug enough not to turn out of spec.. If it is out of whack, seems like it should be covered under warranty.
