The BGM intake manifold allows the use of carburettors with a connection size of 19 mm or 24 mm on these engine casings. The manifold offers a maximum sealing surface to the small engine half.
This allows the manifold to be individually adapted to the respective engine casing. The shape of the BGM intake manifold is designed to minimise the material that needs to be removed from the casing to install the carburettor.
