The UFO is a simple, trouble free, aerodynamic piece that fits VM Mikuni carburetors from 30 mm through 44 mm. 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 and tuning are 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
- 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

Little more than a year ago, the name Geely would happily slip under the radar of most. Today, the Chinese company completed its purchase of Volvo from Ford. Geely stumped up a $1.3 billion in cash for the Swedish brand and issued a $200m note.

Honda Clarity Hydrogen Fuel Cell Car - already in the real world at $600 a month
We make no secret of the fact that we consider Hybrid cars a stop-gap solution to reducing reliance on oil. And frankly, unless you drive like a saint you’ll probably find you get inferior performance and poorer fuel consumption out of regular hybrids than you would from a decent eco-diesel. Only when you start to put complex hybrid systems in high-end cars do you start to come up with something that does mitigate fuel use and improve performance.

General Motors has said it will cover half the cost for repairing defective fuel gauges in 2005- through 2009- model-year Chevrolet, Buick, GMC and Saab 9-7X sport-utility vehicles. GM's agreement to pay half the repair costs puts an end to the National Highway Traffic Safety Administration's probe, opened earlier this year. NHSTA was checking into reports that the gauges showed there was more gas in the tank than there actually was.
