Bates Stock Aircleaner Eliminator Kit
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.

VM Adapter Plate for CV Carburetors
VM Adapter Plate for CV Carburetors
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.

Intake manifold for Keihin CV carburetors (from 1989)

Until the late 1980s, Harley-Davidson carburetors were clamped on, but with the Keihin CV carburetor came the change: all Keihin CV carburetors are plugged into the intake manifold. Of course, we have the essential gasket for this in stock for you, as well as the intake manifolds themselves and the connecting parts to the cylinder heads: flanges and ring gaskets with a wedge-shaped cross-section.

The Keihin CV carburetor is held to the cylinder heads on the air intake side by the air filter base plate via two screws. If you don't have or don't want the original air filter, you will have to think about a separate bracket. This is actually a simple and ingenious system.
