The UFO is a simple, trouble free, aerodynamic piece that fits
Mikuni carburetors from 30mm through 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 to 1 HP per 100 cc of engine displacement. (Rejetting and tuning
still annoyed by the erratic high-idle problems so common with larger
Mikuni TM flatslide carbs? If so, here is a product that does an excellent
job at stabilizing the idle speed, but also improves the atomization
of fuel at partial throttle settings. The V.I.P., or Velocity Intense
Performance, is a combination venturi divider and venturi modifier
unlike any other similar device.
Valve is designed to increase air flow into your air box and carburetors.
Racers and tuners as well as many trail riders have known for many
years that opening up the air box in order to flow more air makes
more horse power. They also know that more air means that the engine
will be running leaner exactly the same as installing a smaller main
Drive Clutch springs
are in constant motion, being subjected to compression, rebound, end
to end radial torquing, distortion, and vibration. "Glide Washers"
are custom made with a baked-on lubricity coating. By placing a washer
on each end of the spring it can no longer bind on the spyder or clutch
cover. This frees up the spring to do its intended job. Each kit comes
with 5 washers. Two have a lubricity and rust proof coating and three
are zinc plated to prevent rust.
