Dellorto 17.5mm carburettor for original inlet ports (no additional adapters required). This carburettor is factory-equipped with a 90 main jet and is easy to tune. Carburettors with a 17.5mm opening can be used in sports / medium-race tuned engines. The carburettor is shipped without a choke and a Dellorto butterly choke plate or an electronic choke (E-choke) so must be ordered separately.
The distance between the holes on the mounting plate is 42mm, as with the original, and the air filter opening is 35mm. This means the carburettor can be used as normal with the original air box. With some scooters it can be that the Bowden cable needs to be adapted, which can be done without specialist tools, or a great deal of effort.
This carburettor can also be used as a replacement carburettor for 50cc scooters and a smaller jet may be required.
