Flywheels (and crakshafts) are balanced when they are manufactured. Not sure why they should get out of balance after the fact or need to be rebalanced unless you're building a racing engine or some sort of damage has occurred. Different flywheel weights, the stored energy, will have effect on the dynamics of the engine though.
