Fuel Flow Optimizer - VM30-VM34 - With RH Slide - UFO

The UFO by Thunder Products is a simple, trouble free, aerodynamic piece that fits VM Mikuni carburetors. 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. (Re-jetting and tuning may be required).

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 Reduces cold pipe syndrome Works with stock or modified engines. Designed with deeper throat to fit VM32's better.
