Huh? Vibration throughout The rev range? I-6's don't have that problem if they're balanced. They will get between one and 3 critical points where at a specific RPM they will "sing". But if you know them accelerating though the powerband and passing them as quickly as possible makes them less of an issue. I don't see how having a flywheel too light would exaggerate the issue. Having a heavier flywheel will resist vibration but also exaggerate the issue should the flywheel also reach a harmonic point. Lighter flywheels will not 'absorb' vibration, but they will also not place as much stress on the drive train and crank should they begin to vibrate.
