UFO (Ultimate Fuel Optimizer) for ROUNDSLIDE Carbs ONLY

The UFO is a simple, trouble free, aerodynamic piece that fits Mikuni carbs from 32 to 44 mm. The UFO makes a normal round slide carb out perform the more expensive flat slide carb by eliminating turbulence and increasing airflow and velocity, creating a highly atomized fuel charge. Normal gains are 3/4 to 1 HP per 100 cc of engine displacement. (Rejetting and tuning are required).

Without the UFO, air hits the forward wall of slide cavity creating a rolling air turbulence forcing poorly atomized fuel droplets to the lower portion of carb bore resulting in poor fuel atomization and performance. With the aerodynamic UFO filling the slide cavity, the rolling air turbulence is eliminated. The higher velocity airflow pulls the fuel further up the needle and higher in the carburetor bore resulting in superior fuel atomization.

* More horsepower with less fuel
* Broader powerband
* Explosive throttle response
* Superior fuel atomization
* Less sensitive to temperature, altitude and jetting changes
* Cleaner emissions
* Cooler running engine


Sold per each carburetor. A triple carbureted system will require 3 kits
