Intake manifold -POLINI 2-stud, rotary valve- Vespa V50, PV125 - CS=28.5mm (Dell'Orto PHBL24, Polini CP24 )

The rotary vane intake manifolds for the small frame engines offer the possibility to use carburettors up to 25 mm. With this, quite powerful engines can be realized, which can easily reach the 120 km/h mark. To enable the full performance potential of the engine, the engine housing should always be adapted to the cross-section of the carburettor (as far as possible).
