This two-fold, at best there is 50% can be balanced - then the force of inertia becomes circular (that is, the vector of imbalance, as it turns, rather than jumping up and down or back and forth) with the smallest amplitudes. To completely eliminate the forces of inertia of the first order, you need to either insert the balance shafts from the Oka with gears, or the second cylinder perpendicularly, as on ducati or opposite (but then 2 rod necks are needed).
