BUN FREESTYLE has developed, manufactured and released the world's first 54φ carburetor! Experience power like never before. It is the carburetor that made the double backflip successful. Jets, springs, etc. are already set for freestyle. You can use it as is. *If you have a cap base plate (sold separately, $127 including tax), you can use it if you have a non-WAZ engine.
