Intake manifold -POLINI rotary valve- Vespa PX80, PX125, PX150, PX200, Sprint, Rally180 (VSD1T), Rally200 (VSE1T) - CS=Ø34mm (carburetors Ø28-30mm - PHBH, VHSH, PWK28, TMX30, Smartcarb 26-28)

This rotary vane intake manifold allows the use of larger carburettor diameters. For assembly the original carburettor sump and the original carburettor are completely removed and replaced by the intake manifold. Thereby the automatic oil supply of the engine is omitted with the engines with separate lubrication. Here it must be changed to mixture lubrication. The hole of the oil pump shaft must then be closed with a suitable plug.
The greatly extended intake path of the intake manifolds leads to higher torque on most engines.
