The Dell'orto SI carburetor series features a cylindrical venturi duct.
This very simple shape to produce during manufacturing, however, performs less well in operation compared to carburetors with a conical frustum-shaped venturi duct, as it generates turbulence.
The venturi cone made by Sil-tech PERFORMANCE is designed to address this issue.
Thanks to many CFD (computational fluid dynamics) simulations conducted to derive the best cone profile and various tests performed on the respective motorcycles, a solution has been reached that allows solving the problem of inlet turbulence by developing a specific object for each application.
With the application of a venturi cone, the flow enters less turbulently, achieving a greater air flow entering the engine and an improvement in performance across the entire RPM range.
Designed to occupy as little volume as possible, ensuring optimal operation within the original carburetor box.
TO INSTALL THIS COMPONENT, IT IS NECESSARY TO REMOVE THE ORIGINAL FILTER ELEMENT.
Material: sintered NYLON PA12, ensures chemical resistance to solvents (gasoline and other hydrocarbons) and oils.
