Description
DESCRIPTION
The weight in the arms of a TAPP primary is adjusted two ways: set screws in the arms and washers on the roller thru bolt. The clutch ships with a basic tuning kit. Add weight to lower RPM; remove weight to raise RPM. Set screws in the arms affect the low-speed shift points more than high speed and will reduce max RPM. Weight on the roller axle bolt acts like tip weight, affecting the high-speed portion of the curve more.
STANDARD WEIGHT KIT INCLUDES:
- Eight (8) 1/2 inch Allen screws
- Four (4) 1-1/2" Roller Bolts
- Four (4) 1-3/4" Roller Bolts
- Four (4) 2" Roller Bolts
- Four (4) Nylon Nuts
- 16 regular washers
IMPORTANT - Make adjustments evenly and only in pairs across from each other to avoid imbalance and possible failure. Allen screws must be added in pairs opposite one another. Allen screws are .500' weighing 2.7 grams. Adding two Allen screws will add 5.2 grams. Adding all eight Allen screws will add 20.8 grams.
