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, 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. 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. 
 

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 - As with all other adjustments, do this evenly and only in pairs across from each other, failure to do so will result in an imbalance of the clutch and possible failure.

 

Allen screws must be added in pairs opposite to 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.

Evolution Powersports has a reputation of the utmost quality and attention to detail on every product they design. From within the industry and outside, I have heard nothing but great things about this company and my experience has been the same. If you are looking to make more reliable power this company can get you there. Both customer service and product design are top notch and they stand behind their work!

If you truly want to build your project with the best possible parts available, buy EVO. They not only build with the best materials they test and test to make sure you are getting the performance gains they say you will but that the mods will be safe and keep the reliability of the machine as high as possible. Thanks again to both Jim and Todd. Keep it up guys!
