A variable speed belt drive having adjustable mass and moment of inertia camweights is shown for use primarily in conjunction with snowmobile, golf cart, all terrain vehicle and small automobile engines. In one version, the camweight includes a series of perforations or score lines surrounding a cross section of the camweight arm. The perforations define a volume that may be snapped or cut off of the arm with a suitable tool. Also, a series of bores are formed through the arm. In order to increase the mass of the arm, a molten metal or similar flowable material may be poured into one or more of the bores and allowed to cure. In another version of the invention, a reduced cross section arm serves as a base onto which shims are added or reoriented in order to achieve the desired mass and moment of inertia characteristics.
