Weber Twin Update Kit fits 40mm IDF:
Power up your Weber's with this new IDF Update Kit. You'll get increased torque, acceleration, and more top end with this all new energy package.
The IDF Update Kit features horizontal spray bars that replace standard bulls eye secondary venturi to produce improved atomization through the power band.
Longer taper flow main venturi to improve airflow and special calibration are also included.
Each Weber Update Kit also includes a complete gasket and O-ring kit. It's not black magic, just another example of CB's creative engineering and dedication to true performance.
IDF Update Kits are available to fit 40 and 44mm Weber IDF Carburetors. Each kit is designed to convert two carburetors to fast track horizontal spray bar discharge.
This is a straightforward parts replacement installation. Machining, drilling, or altering of the carburetors is not required. If you can get your tool box open, you can quickly pump up your horsepower with this 'easy to install' kit.
