Description Ultimate Flow Optimizer. A simple, trouble free, aerodynamic piece that fits Mikuni carburetors from 30mm to 44mm. 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 HP to 1 HP per 100cc of engine displacement. (OD on 36mm UFO=1.380″, 38mm UFO=1.415″)
