I think the harmonic balancer is specifically to address the big
harmonic at around 5200 ish RPM. What happens to the crank harmonics
when the weight at the back of the crank changes?

A heavier flywheel just takes a bit longer to get up to the higher
revs but the total max rpm is the same. If it is balanced
properly, there is no change to vibration. Most race cars utilize
