Sidewinder Suzuki Samurai CV Harley Carburetor Installation Kits

Sidewinder CV Harley Carburetor Kits

The Sidewinder CV Carburetor kit for the Suzuki Samurai allows you to install the popular Keihin® 40mm CV (constant velocity) or the Screaming Eagle 44mm side draft carburetor on your stock or modified off-road vehicle. The performance and reliability of this carburetor is a matter of record, and with its float bowl below the venturi, the Keihin is very resistant to flooding or rough running when operating on steep inclines or angles. The constant velocity system smooths sudden throttle changes and also allows the Keihin CV to automatically alter A/F (Air/Fuel) ratios during elevation changes.

By far the easiest and most simple way of increasing the ponies from your Samurai Engine. CV Carburetors flow better, run on angles better and increase efficiency better than any carburetor available for the Samurai.

What makes this sidedraft carburetor kit different?  

  • The carburetor brackets allow for easy removal of the carburetor itself.
  • Carburetor sealing is ensured by using unique adapters for 40MM or 44MM Carburetors.
  • Better vibration resistance than competitors. 
  • Free flowing manifold machining.
  • Carburetors can be tuned for additional upgrades (Cam, Header, Internal Engine Upgrades)


  • Brackets needed for installation of Carburetor to 1.3L 8V Carbureted Manifold
  • High Quality K&N Air Filter
  • Installation Hardware
  • Hoses and Hose Clamps
  • Adapter to Manifold Gasket
  • Valve Cover Filter
  • Proper Length Choke Cable and Knob

This kit  includes installation instructions and additional instructions on how to modify your supplied carburetor for optimum performance.

What Else Do You Need?

You will need to modify your throttle cable or purchase our modified cables from this page. 

Sidewinder Kits do not include a Carburetor.  You will need to source either a 40mm or 44mm Screamin" Eagle Carb.  

Here are Three Suggestions:

1) Purchase Direct From Sidewinder.

We now include with each 44mm kit a New Genuine Harley Davidson 44mm Screamin' Eagle Side Draft Carb (SEU-CV44) that is pre-modified for use on the 44mm Sidewinder Kit. This is the easiest way to go.  When you order both the carb and adapter kit together you will receive them ready to install.

3) Purchase a Used 40mm or 44mm

Many customers prefer the 40mm carb to the 44mm as it tends to be easier to adjust and more forgiving in altitude adjustments.  Unfortunately it is no longer available new.  Used 40mm carburetors must be manufactured between 1996-2006.  

If using an old carburetor please see the parts table below and make sure you have all the necessary choke parts.  Because these parts are included with new carburetors, we do not include them in the Sidewinder kit  but they can be purchased from Harley Davidson by requesting the part numbers listed below.

Please Note:Please Note: Carburetors need to be modified before installation.  You can do it yourself using our instructions.
