Airflow has been significantly increased by opening the venturi to the max limit of .615 using a CNC machining center - the same technology we use to bore our connecting rods.  The carburetor will be jetted for your application.  Will pass AKRA and NKA box stock tech. Also a great carb for the Predator 212cc engines and for applications other than karting such as Mini Bikes, Drift Trikes, Bar Stools or Mud Motors. The carb will come jetted for open air filter. If using a Factory Stock Air Box please call 800-521-3560 to order. The jetting is different for that application. 


We jet these carbs specific to your application. The carb will come with instructions for timing and coil gap recommendations.  Please select which restrictor plate you are using, which header configuration you are using, your type of racing and your cam from the drop-down boxes so we can customize your carb to match your needs. Carb is set up for Gasoline fuel only.
