On a theoretical note: Isn't the flywheel meant to store the energy imparted to the crank between the power pulses? And if that is the case, doesn't a lighter flywheel tend to cause the torsion differential between the pulses on the crank to increase versus a heavier flywheel which will tend to store the energy longer. This is comparable to what a filter circuit does in electronics. If I reduce the capacity of a filter, then the ripple voltage will increase, especially under heavy loads. Perhaps a heavier flywheel should be considered, especially in an engine which is being increased in its power output. I'd be interested in hearing the science on this.
