I have two MAXs, one balanced and the other non-balanced, and the balanced feels so much heavier... Gotta weigh em in I guess
The crankshaft in a one cylinder engine has always been a debate, myself I don't think it's possible I believe the weight is there to move the resonance frequency higher to get higher rpm's when metal inside an engine starts resonating it's hard to get past that vibration point and get speed.
Heavier/denser resonates much later = no vibration barrier to compete with.
Most high end crankshafts are lighter, but the slugs in the counter weights are denser.
But that's just an educated guess
