21mm PWK racing carburetor

Ok for racing! This PWK replica is a big carburetor that can increase your scooter's performance. The larger diameter venturi and intake funnel offer lower resistance through increased laminar flow and reduced flow losses. This carb can give you more power, torque and better response and is especially beneficial to big bore engines or tuned engines. Works best with a big manifold, please see the 'Intake' category for the right one for your bike. This PWK type carburetor features technology developed for racing engines, including: chrome flat slide optimum funnel shape for fastest intake flow  high flowing venturi plug at bottom of bowl for quick jet swaps manual choke mechanism (lever sold separate) This suits all performance 2 and 4 stroke engines 50cc - 125cc. For two strokes, you should run premix but it is possible to drill the blanked nipple and use your own fitting, if the manifold is not fitted with one. The carburetor body is physically bigger than some factory ones, in some rare cases there may not be enough room to mount it exactly in the factory position. Some intake modification may be needed for some scooters, and some scooters will need the additional throttle cable (product code G2003). Recommended for use with one of our 50mm pod filter or funnel options. (carburator, carburettor)
