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.<br />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.

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.

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 (exc. CV) bolt pattern. It is also useful with large or low mounted gas tanks, because it positions the air cleaner further to the right by 25 mm.

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

These brackets allow, in combination with a custom support for Big Twins 1990-1999, for an easy and solid installation of a CV carburetor to Shovelhead engines late 1978-1984. They bolt to the underside of the rocker boxes. <br />As there are some tolerances in the placement of the threads in the rockerboxes and various manifold adapters on the market,spacers may be required.

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.

"The installation of a a CV carburetor with Custom air cleaner on a Panhead, Shovelhead or Ironhead Sportster involves two problems:<br /><ul><li>the protruding upper carb end interferes with the commonly flat backing plates of accessory air cleaners</li><li>omission of the stock CV air cleaner results in an unsupported carburetor</li></ul><br />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.<br />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."

The Thunderslide kits contain a specially designed slide made from plastic. The benefits are its extreme light-weight and a faster throttle response.<br />Compared to the stock part, the cut-out and pressure compensation bores are redefined which adds efficiency and mid-range power, and lowers fuel consumption.

Improve the performance of stock 40 mm Keihin CV-Carburetors. These kits contain all necessary jets, needles, springs and a detailed instruction that leads you step-by-step through the carb tuning and modification for maximum performance on stock motors as well as on motors with performance cams and exhausts. More power throughout the complete RPM-range and better throttle response. Especially recommended when you switch to a Custom air cleaner.

High-quality, low priced alternative to our Dynojet kit. Contains the same components, including 5 main jets (1.50 to 1.90) and permits to improve the performance of the stock CV-Carburetor as used from 1989 to 1999 on Evolution Big Twins. Fits carbs with or without accelerator pump.

Nice accessory that neatly installs over the stock black plastic knob on all XL 1988-2006 and Big Twins 1990-2006 with CV carbs. It not only looks 100% better, with its knurled edge it is also easier to hold and operate.

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.

Cast aluminum manifolds for Evolution engines with Keihin CV carbs.

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 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. <br />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.
