Matching pair of bmw R80 or R100 Bing 32MM carbs.Matching # pair 64/32/357 and 64/32/358. In very nice condition. Really clean, see pictures.

Pair of Bing constant velocity (CV) carburetors, specifically the "flat top" or flat dome cover design commonly used on classic BMW Airhead motorcycles (such as the R45, R65, or early R80 models).

Key Details About These Carburetors:

Identification:

The black plates clearly display the "BING" logo. Stamped into the metal bodies near the mounting flanges, you will find the specific model numbers (typically starting with 64/26 or 64/32), which dictate the bore size and exact factory jetting specs.

Orientation:

They are a matching pair consisting of a distinct left-side and right-side carburetor. This is evident by the mirrored orientation of their choke mechanisms, throttle linkages, and fuel inlets.

Function:

They use a vacuum-operated slide diaphragm mechanism underneath the flat top lids to automatically adjust fuel delivery based on engine load, ensuring smooth throttle transitions on vintage twin-cylinder boxer engines.

A matched pair of Bing 32mm constant velocity (CV) carburetors.

The specific identification stamped numbers 64/32/357 (left side) and 64/32/358 (right side) correspond to original equipment components for late-model BMW Airhead motorcycles.

Compatibility & Technical DataPrimary Fitment:

These exact numbers were factory equipment on late-production BMW R80GS and R100GS / GSPD dual-sport motorcycles.

Alternative Fitment:

They were also utilized on late-era road models such as the 1995 R100RT and R100RS.

Design Characteristic:

The "64" specifies the carburetor type (Constant Velocity), while the "32" indicates the 32mm venturi bore diameter. Late versions like the 357/358 series feature leaner factory jetting curves designed to meet stricter emission standards.

These specific Bing 64/32/357 and 64/32/358 carburetors fit 1990 to 1995 BMW Airhead motorcycles. They were introduced for late-production models to meet stricter emissions standards.
