Our thanks to Venice area scooter parts specialist Bettella for information about its new Pinasco programme stock replacement upgrades for Vespa applications.
Seen here for Vespa 5%, 2-port wide frame models (most Vespas from 1954-’58), Pinasco’s 24/22 carburettor kit is available for models with or without intake manifold and only needs main jet adjustment.
The package includes everything needed for assembly, including a specific air filter which “perfectly fits into the carburettor space in the frame without modifying any original component.
The kit uses model-specific Dell’Orto carburettors, which have readily available service parts and replacement components.
Courtesy of ScooterLab.uk, Roger Green of British vintage Vespa specialist Wessex Scooters reports that “the carb fits onto the 24 mm inlet manifold used with the Pinasco 160 cylinder kit and can also be used with other wide frame tuning kits which use the 24 mm inlet manifold.
“The carb includes a specially designed throttle arm which allows full slide travel with the original wide frame handlebar throttle configuration and a slim high-performance air filter which keeps the required gap between the carb compartment door. The mixture can be adjusted easily with the carb mounted due to the location of the mixture screw.”
Also seen here is the Pinasco carburettor for large frame Vespa models, with a Venturi, a 5 mm higher gasoline bowl than the classic - to avoid fast emptying of fuel and bigger gasoline channels and allow the maximum flow of mixture (not available in MIX version).
The Pinasco Racing Bull clutch (also for large frame Vespas) is made up of a 12 spring, high-strength steel bell and full grafting system. This clutch unit has been designed to increase the power transmitted by the crankshaft to the gear set and has been tested up to 38CV of transmitted power.
“The swallowtail bushing/bell system avoids dragging discs even under toughest working conditions. The Pinasco Racing Bull clutch comes with two different types of springs with different hardness, to set the product according to requirements, and a bushing and a brass spacer.”
