Carburetor-intake boot adapter for Vespa Largeframe

Handcrafted stainless steel adapter, connection width suitable for Polini PWK 28 and Keihin PWK 28 carburetors.
With this adapter, the original intake bellows can be used with the frame; the carburetor is thus supplied with cooler air, and the intake noise is significantly reduced.
This intake solution fits almost all Vespa largeframe models that use a PWK 28-30mm carburetor mounted perpendicular to the direction of travel, as is the case, for example, with the Malossi VR-one engine casing. It is also compatible with Scooter & Service and MRP reed valve systems – we use this adapter in almost all Vespa projects with a PX engine and reed valve intake.
The intake bellows adapter is supplied including a suitable hose clamp for attachment to the carburetor.
