SI VRX 20 Carburetor With Mix

The Pinasco VRX-R carburetor, with recalculated and billet intake horn, was created to optimize the performance of the Vespa SI Pinasco carburetor. The Venturi horn has been calculated to increase the volume of air sucked in by the carburetor; the increase in performance is noticeable from low revs. Pinasco recommends mounting the VRX-R carburetor together with the Pinasco .
