Abstract: A spin balanced crank assembly for two-stroke and four-stroke engines, such as those used in snowmobiles and ATVs, is provided. The crank assembly may achieve an overall two- plane balance engine by adding two additional masses to opposing sides of the crank assembly. The additional masses are each unbalanced to a desired amount and angle in order to offset unbalance in the engine and obtain a balanced assembly. The amount of weight to be added or subtracted may be attached to the masses may be determined by the size and engine from which the crank assembly is a part of because the angle of unbalance of the crank assembly is know beforehand. Additionally, methods for spin balancing two-stroke and four-stroke engines are provided, wherein the method comprises balancing the engine without disassembling the crank.
