An adjustable mass clutch weight for use in a CVT clutch is provided. The adjustable mass clutch weight may include an elongate body having a heel and a tip; a first protrusion having external threads extending from a first side of the elongate body at the heel. The adjustable mass clutch weight may also include a second protrusion having external threads extending from a second side of the elongate body at the heel. The adjustable mass clutch weight may also include a mounting aperture extending through the first protrusion, the elongate body and the second protrusion; and at least one mass adjustment weight with a threaded aperture extending through the at least one mass adjustment weight. The at least one mass adjustment weight may be coupled to the first threaded protrusion and/or the second threaded protrusion to adjust the mass of the adjustable mass clutch weight at the heel of the elongate body.
