ABSOLUTELY NO ONE SUPPLIES A MORE COMPLETE KIT...NO ONE!

These are two split carburetors, not side by side. The split single kit eliminates the restrictive OEM manifolds and provides a straighter, less restrictive path into the combustion chamber which maximizes torque and horsepower.  This kit will NOT work with the OEM intake manifolds and so aftermarket units are required.  The typical set-up is to use two rear manifolds along with one downdraft and one horizontal draft carburetor which allows the straightest shot into the cylinders.  This is the only way to achieve and surpass the 100HP barrier!

This kit is suited for mild to modified motors and will come pre-jetted for immediate bolt on installation.  Tuning and performance specs have been developed over the years to suit a wide variety of conditions, however some fine tuning may be required to attain the desired combination of performance, fuel mileage, and drivability.   Extra main jets are included for fine tuning and additional Genuine Keihin parts and accessories are always available at low prices.  Alternatively kits can be built utilizing your own jetting specifications.

WARNING: This carburetor kit will seriously wake up your machine!

They don't include all the necessary items for a successful installation and that forces you to buy more items, possibly at a higher cost.
