BGM FASTER FLOW SI Carburetor - optimized carburetor for high-performance engines

High-performance engines require reliable and consistent fuel supply. The BGM FASTER FLOW carburetor is designed to meet these needs, using the Dell'Orto/Spaco SI24/24E or SI26/26E models. Each unit is completely disassembled, tested, reworked, cleaned, and carefully reassembled in our factory, ensuring the highest quality for modified engines.

Main modifications:

Enlarged connection holes from the float chamber to the nozzles
Added a hole in the float needle area
Spring-loaded float needle for increased durability
These modifications significantly improve fuel supply, preventing shortages even with powerful exhausts. In particular, the spring-loaded float needle compensates for vibrations and increases durability, while the optimized supply is also advantageous for stock engines.

Advantages:

No nozzle blockage with powerful exhausts
Easy tuning even with over 20 HP
Quiet, powerful, and suitable for everyday use
Available for mixed or separate lubrication
Suitable for:
Engines with SI20/20D or 24/24E carburetors

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.
