Even "internally" balanced engines generate vibrations since the reciprocating masses are not rotating perfectly co-planar (the rod journals are offset from one another).
This causes vibrations that can be partially nullified by a harmonic dampener attached to the rotating mass.
And I fully understand engine balancing as I paid extra for it to have my racing boxer engine balanced.
And even though a boxer engine is "internally balanced" they still wanted to balance the entire rotating mass as a unit, and did not balance the front pulley & FW separately (for the final balance)
