NOTE: All new Si carburettors are manufactured under licence by Spaco in India. These carburettors have been and are used in the series production by Piaggio for a long time. They are of the same quality as the original Dell'Orto carburettors, and ironically far better quality than the Spaco branded ones. They also pass the quality assurance at Dell'Orto, come directly from Dell'Orto (Eurocarb) and are delivered in Dell'Orto packaging.
