Quality clone of the Dellorto PHBG Racing Edition Carburetor. The most noticeable feature of this 21mm carb is its black color. The metal float bowl is equipped with a central screw that allows you to easily change the main jet. Thanks to the threaded cap for the throttle slide, you can easily change the needle without having to take the complete carburetor out of the manifold. The new way of jetting also prevents an overly rich mixture. The carburetor has an oil feed and vacuum connection and so is ideal for daily use. Best paired with larger cylinder kit and performance exhaust.
