They made it so heavy to damp the impulses from the compression stroke and combustion stroke on the unslung (uncounterbalanced) crankshaft. If you add slings - or, obtain a slung crank - to your crankshaft, then you have partial damping under each piston and you do not need the weight of the original flywheel to damp the crank at the aft end of the crankshaft. Experiments we have done here indicate that removal of twenty pounds is the best practical amount to remove from the stock flywheel, thirty pounds if you want to produce a performance engine. One big caveat though: you are going to have to tune your ignition spark with the lightened flywheel. You can't just set it and forget it. Particularly retarding it a bit when on certain inclines. Happy Motoring!
