What to do if you're looking to add a little oomph to your Ninjette? Keihin's new Special CR carburetor is a racing-spec unit with what they call a "smoothbore venturi for high air flow and precise fuel meeting," and the added airflow means you'll squeeze more horsepower and torque out of the 249cc parallel twin.
The twin carb kit is compatible with 2008 and 2009 Ninja 250Rs, and works with stock throttle cables but can be paired with a modified airbox or tuned velocity stacks. Retailing at $455, the Keihin carb kit is available at sudco.com-- but note that the unit is intended for race use, and will most certainly trim the Kawi's rated 61 miles per gallon.
