"....and is there a relationship between the mass/diameter of the flywheel (and clutch?) and the mass/diameter of the harmonic balancer?"

That’s true of course. But if I’ve understood correctly, both the flywheel/clutch combo, and the harmonic balancer are responsible for absorbing the harmonics, or resonances, that result from multi-sourced vibrations. Some of the resonances come from the torque transferred to the crank from each piston after combustion. So...it would seem logical that you don’t just slap on any convenient (zero balanced) harmonic balancer, as the HB and the flywheel need to work as a pair, so need to be sized to complement each other. IMO.... but really I’m just guessing, which is why I’m asking....
Cheers,
