A stainless steel bracket which allows you to relocate your CV-Carburetor choke cable - without disassembly - to the right side of your Sportster, FXR, Dyna or Softail. Mounts switches or the like, too, of course.

Idle adjustment of Keihin carbs can be annoying because the adjusting screw is somewhat hard to reach, in particular with stock air cleaners and large gas tanks. The Bates adjuster solves this problem once and for all. It features a flexible shaft and a large adjuster knob with knurled edge which allows carb adjustment without a screwdriver and as fast as you can say "****! I forgot my ******* tool roll in the garage!"

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.

If you own a Shovelhead, Panhead or Ironhead Sportster, this bracket is for you. It allows attaching a CV carburetor to 2-bolt Tillotson, Bendix or Keihin (butterfly) manifolds. The bracket even has a mount for the CV-carburetor choke cable. Longer screws and little spacers to go to the carburetor lid are included.
Depending on configuration, installation might require:
2-bolt flange adapter, carburetor support bracket, air cleaner spacer 3mm, gaskets,
Please acquire these items separately.

These Mooneyes idle adjuster screws facilitate the adjusting of the idle speed and, with the cult Mooneyes ball, also cut a fine figure. The ball can be unscrewed and replaced with other Mooneyes valve caps.

Originally developed for race bikes to speed up jet changes but today they are popular among street riders, too. The set comprises four screws with large knurled heads for easy installation and removal of your float bowl without tools.

The selection of air horns, velocity stacks and carb covers for Linkert carburetors is pretty extensive and many of them look nicely at home on a CV-carb, too. With this little adapter plate you can make this happen in no time. Precisely CNC-machined from billet for a hassle-free installation.
Since the bolt circle for Linkert carbs is smaller than CV carb bolt circles the adapter somewhat restricts the air intake. All you performance nuts should consider this.

This adapter allows for the installation of OEM or aftermarket air cleaners with recessed backing plate on Keihin CV carburetors. At least that’s what it is intended for, but of course, you can mount any air cleaner, carb cover or air horn with a Tillotson, Bendix or Keihin bolt pattern. It is also useful with large or low mounted gas tanks, because it positions the air cleaner further to the right by 21 mm.

Rubber adaptors to mount spigot style carbs like Mikuni, Dell‘Orto, Keihin CV, etc. to manifolds with two-bolt flange.

The adapter flange allows for easy and secure mounting of a CV carburetor on Bendix and Keihin throttle body manifolds. This makes it possible to use the popular Harley-Davidson CV carburetor on a wide range of vintage models, including Knuckleheads, Panheads, Shovelheads, as well as Sportster models up to 1987 and Evo Big Twins up to 1989.
Manufactured from high-strength aluminum and CNC-machined, this adapter impresses with precise craftsmanship, durable quality, and a perfect fit. It is equipped with a specially designed O-ring that ensures a reliable seal and minimizes the risk of leaks. The attachment is achieved through press-fit onto the carburetor, with cold metal compound available for secure fixation if needed. An additional gasket is generally not required.
It is important to note that the press-fit is permanent and cannot be reversed without damage after installation. When installed carefully, this technique provides an absolutely tight connection, reliably sealing out any air leaks and ensuring optimal engine performance of your Harley-Davidson.

These kits are designed to support CV-Carburetors on models equipped with the cylinder head crankcase breather system, when mounting custom air cleaners that lack the support.

Even with an angled screw driver adjusting your Keihin's idle mixture is no fun. Swap your stock adjuster screw againts this knurled head adjuster, and you are at ease: Idle mixture adjustment with just your finger tips!
