Balancing Crank Assembly

The flywheel assembly should be balanced to minimize the forces that would occur from an out of balanced assembly. This mainly helps the engine run smoothly. An out of balance assembly increases wear on the bearings, increases vibrations throughout the engine and can reduce the engines power output. Replacing the flywheel with a modified lightened one will lighten the crank assembly. This has the effect of reducing the inertia of the heavier flywheel, allowing the engine to revolve easier soaking up less of the produced power. However this loss of inertia also makes the engine easier to stall at low revs.
