for Keihin CV Carburetors

Cast aluminum manifolds for Evolution engines with Keihin CV carbs.

"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."

This plate allows installation of CV carburetors on Bendix and Keihin (butterfly) manifolds. Thus you can use them on Knuckleheads, Panheads, Shovelheads, Sportster →1987 and Evo Big Twins →1989. Precisely CNC-machined from billet aluminum, with special O-ring. The adapter plate has a press-fit on the carburetor, optionally using a cold-weld compound. No other gaskets necessary.
Unfortunately, this press-fit cannot be reversed without damage to the parts. This may seem radical, but it guarantees absolute tightness, provided it is properly installed and zero air leaks will influence the bike's performance.
