The highly sought-after reproduction of the original carburettor casing is back! With an optimized carburettor and housing sealing surface, precise craftsmanship, and premium materials, it’s the perfect solution for tuning and restoration projects.
Why the SIP Carburettor Casing is a Must-Have for Vespa Fans
Many engine builders working on performance-enhanced tuning engines deliberately avoid relying on the classic Piaggio oil injection system. Instead, they turn to the proven method of manual oil-fuel premix – just as it was used on all Largeframe Vespas before the introduction of the oil pump, such as the legendary Vespa Rally. Internationally, this system is also known as Autolube.
Authentic Reproduction in Premium Quality
The SIP carburettor casing impresses as an authentic reproduction of the classic component. It is manufactured by a reliable producer who places great emphasis on high-quality materials and precise craftsmanship.
Special Features:
- Exact reproduction of the original
- Enlarged sealing surface for larger carburetors
- Flow-optimized channel design for maximum performance
Technical Advantages at a Glance
While most specifications closely follow the original, the carburetor and housing sealing surface has been cleverly enlarged. This allows the use of larger carburetors (20–26 mm diameter).
For even more performance, the CNC-milled carburetor casing SIP PERFORMANCE CNC and SIP PERFORMANCE CNC in black are also available, specifically designed for 28 mm SI carburetors.
The models Carburetor Tray SIP (elongated inlet) and Carburetor Tray SIP (round inlet) differ only in the inlet shape. However, both versions are perfectly matched to the flow characteristics of the engine housing channel, ensuring maximum efficiency.
Installation Tips
A clean carburetor is half the battle, so make sure to clean it thoroughly and use a fresh gasket set right away. The float needle should also always be replaced, as it is often the source of problems. Don’t forget the rubber plug for the idle mixture screw. If the adjustment screws are rusted tight, it’s better to replace them with the special-thread version to be on the safe side.
Conclusion: Perfect Combination of Tradition and Tuning
Whether it’s a restoration project or a high-performance tuning engine, this authentic Vespa carburetor tray is an essential upgrade. With its enlarged sealing surface and top-quality workmanship, it blends the classic Vespa feeling with modern performance.
