Motorcycle Parts

The 2011 Kawasaki lineup of fuel-injected motocross machines is here, and the newly redesigned KX250F will be joining the veteran KX450F in its adoption of high performance fuel-injection systems.

Fuel injected machines offer riders excellent throttle response and power delivery in a wide variety of riding conditions, but to get the best out of these machines the fuel map often needs to be adjusted.

The Yoshimura PIM-2 unit and DATA Box accessory allow you to do just that, giving you improved throttle response and a great boost in performance.

The PIM-2 is easy to install, simply mount the unit using the included mounting hardware, plug it into the stock wiring harness, choose one of the two preloaded fuel maps, and it takes care of the rest! The two included maps are designed for use with a Yoshimura slip-on exhaust or full-system, but there are additional maps available for download on the Yoshimura website.

For the ultimate in fuel-map customization, just add a Yoshimura DATA Box accessory.

This data acquisition kit automatically calculates the required air/fuel adjustments required at each RPM/throttle position to reach the user-defined target ratio, then it generates an optimized custom fuel map for use with the PIM-2 unit.

Translated, that means you’ll get great power and throttle response at every RPM and throttle position, without spending all of your time and money on an expensive dyno session.

Both the PIM-2 and DATA Box accessories include all of the necessary mounting hardware and easy to follow instructions for a quick install. Installation of the DATA Box may require some modification of the exhaust system to receive the included oxygen sensor.
