UFO Ultimate Flow Optimizer for RD’s and RZ’s

$72.50

The UFO Ultimate Flow Optimizer is a simple, trouble free, aerodynamic piece that fits VM Mikuni carburetors from 26-28mm. The UFO makes a normal round slide carburetor out-perform the more expensive flat slide carburetor by eliminating turbulence and increasing air flow and velocity, creating a highly atomized fuel charge. Normal gains are 3/4 to 1 HP per 100 cc of engine displacement on 4 stroke engines and 1 1/2 to 2 HP per 100cc of engine displacement on 2 stroke engines. (Minimal rejetting (pilot jet) and tuning are required).

Note: This UFO kit is for twin cylinder engines and includes 2 UFO’s.

When installing UFOs, the pilot jet must be reduced substantially (usually about 50%, sometimes even more)

Fits in your existing carburetor slide – kit does not include slide.

More horsepower with less fuel

Broader power band

Explosive throttle response

Superior fuel atomization

Less sensitive to temperature, altitude and jetting changes

Cleaner emissions

Cooler running engine

Easier starting and warm-ups

Eliminates cold pipe syndrome

Works great with stock or modified engines

 

Without the U.F.O., the air hits the forward wall of the slide cavity creating a rolling air turbulence which forces the poorly atomized fuel droplets to the lower portion of the carb bore resulting in poor fuel atomization and poor performance.

With the aerodynamic U.F.O. filling the slide cavity, the rolling air turbulence is eliminated. The higher velocity air flow pulls the fuel further up the needle and higher in the carburetor bore resulting in superior fuel atomization. This means more HP, quicker throttle response, improved fuel economy and a cooler running engine.

UFO and Dial-A-Jet

We are frequently asked how or if the UFO works with a Dial-A-Jet. The answer is they work great together. When a UFO and Dial-A-Jet are used on the same carburetor you have a very high tech carburetor at a reasonable price. Due to the carburetor’s newfound ability to atomize fuel more efficiently, your engine can produce maximum horsepower and torque under all conditions without changing jets. The chart will show you where each product is most effective. As you can see by the chart, they compliment each other.
