Deskripsi Produk
A SI 26/26 VXR carburettor, produced by PINASCO, including a CNC machined Venturi funnel. These carburettors already possess the larger float chamber initially found on the original carburettors included with the Vespa COSA models. The size of the float-needle mounting has also been increased, along with the diameter of the fuel supply opening, eliminating the problems of fuel starvation encountered when combining SI carburettors with tuned motor set-ups.
