The weight in the arms of a TAPP primary can be adjusted in two ways: set screws in the arms, and washers on the roller thru bolt. Your clutch was shipped with a basic tuning kit. As with all other clutches, add weight to lower RPM, and remove weight to raise RPM. Set screws in the arms affect the low-speed shift points more than the high speed and will reduce the max RPM. The weight on the roller axle bolt acts like tip weight in a conventional clutch, affecting the high speed more than any other part of the curve. Adjust this as needed for your application.
