Each arm can be assembled with tungsten and steel washers that can be used in various combinations to achieve the desired operating RPM. The SUPERTIPS will fit STM primary clutches with 5/16" non-fixed pins. Our tungsten washers weigh 7 grams each. There is no other arm on the market that allows this wide range of adjustment.
