O.k. - the V-6 is always unbalanced, firing-wise correct (2 on one bank, 1 on the other or similar). This is a second order rocking motion - correct?. I guess that rotationally a V-6 can be balanced (first order -?). Are these both torque (rpm) sensitive? Would a weighted fly-wheel do anything for non-rotational ( other than first order) unbalanced?

I'm an EE so excuse my lack of knowledge.
