Bates Stock Aircleaner Eliminator Kit
"The installation of a a CV carburetor with Custom air cleaner on a Panhead, Shovelhead or Ironhead Sportster involves two problems:
the protruding upper carb end interferes with the commonly flat backing plates of accessory air cleaners, omission of the stock CV air cleaner results in an unsupported carburetor,
This smart kit inludes a 3 mm spacer plate, which resolves the first problem and a flange adapter with two spiral springs to connect spacer and plate and thus safely hold the carburetor in its rubber flange = resolution of the second problem.
Will fit all motors with 2-bolt Tillotson, Bendix or Keihin (butterfly) manifolds. Installation also requires a 2-bolt flange adapter and a carburetor support bracket, which both need to be purchased separately."
