October 3, 2007 – Ogden, UTAH – With the help of R&R Cycles, PSI has developed a carburetor with modern technology that can and will make your bike run as well as it looks. The 3-D carbs are 100% American made and PSI guarantees you'll see HP gains of 6-15 HP in most cases. With its clean look and a three-year warranty, the 3-D carbs have a much larger billet float bowl design with more fuel capacity, significant cylinder clearance, an optional dual cable pull and three flat-slide designs, making them the ultimate setup for any engine size.

With a very unique shape and a ribbed interior that truly intensifies flow characteristics, PSI's 3-D carb offers much more torque and better acceleration than standard V-Twin carbs. Vortex Generators take total control of the air and align it for maximum port velocity, allowing big HP gains. A shorter throttle pull, a new easier-to-use external needle adjuster, very tight slide clearance, highly developed slide and needle combinations allow for incredible throttle response, serious midrange snort, and a smoking top end all come standard on a 3-D Big Air carb.

Carb adjustments are made easy by turning external clicker adjustments with the simple and easy concept of "righty-tighty and lefty-loosey." Turn clockwise for less fuel and counter clockwise for more fuel – while the bike is running. No jets to change, all adjustments are made externally in seconds without fuel on your fingers or tools in your hands.

The flatslide design with V-shaped technology offers incredible volumetric efficiency. Highly mystified fuel vaporization keeps fuel in suspension throughout the intake process for incredible throttle response and awesome acceleration. Easy and direct replacement for all S&S bolt-on
