The Tusk Carburetor Rebuild Kit makes it easy to rebuild your old worn out carburetor on your motorcycle or ATV to ensure peak performance. The carb kit components are made to OEM specifications and will include OEM sized jets (be sure to have your machine selected to see exactly what comes in your specific carb kit). When cleaning the carb, be sure not to spray or get any type of cleaner on the rubber components of the carb. This will cause swelling and damage to the part.
