The UFO Ultimate Flow Optimizer is a simple, trouble free, aerodynamic piece for stock RZ350/Banshee carbs. 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 re-jetting (pilot jet) and tuning are required).
Note: This UFO kit is for twin cylinder engines and includes 2 UFO's.
