Now offers you the well-known and well-tried Dellorto Racing carburetors. The most noticable feature of the 21 mm carb (type PHBG) is its black colour. The metal float bowl is equipped with a central screw that allows you to easily change the main jet, the way you know it from Arreche carburetors. Thanks to the threaded cap for the throttle slide, you can easily change the needle without having to take the complete carburettor out of the manifold. The new way of jetting also prevents an overrich mixture. The carburettor has an oil feed and vacuum connection and so is ideal for daily use. Same performance as predecessor, but equipped with plenty of new, handy features.
