The carburettors of the same series only differ in their vehicle-specific equipment. This can be adapted however completely problem-free to each new application. Thus a 20/20D can also be suitably re-equipped for operation with a larger cylinder.
SEPARATELUBRICATION
Carburettors for vehicles with separate lubrication can also be used on vehicles without separate lubrication without any problems.
TUNING
If a larger cross-section is to be used, the SI20/20D carburettors can easily be exchanged for carburettors of the SI24/24E or SI26/26E series.
Likewise, older vehicles equipped with a smaller carburettor, such as a 20/15 or 20/17 SI, can be converted to a 20/20.
In both cases, the jetting must be adjusted accordingly.
NOTE: All new SI carburetors are manufactured under license by Spaco in India. These carburettors have been and are still used in Piaggio's series production for a long time. They are of the same quality level as the original Dell'Orto carburettors. They also go through the quality assurance at Dell'Orto and are therefore partly also delivered packed in Dell'Orto boxes.
