Intake manifold - for reed valve -MRP- for Polini reed valve in Vespa V50, PV125, ET3 frame - CS=Ø34mm (carburetors Ø28-30mm - PHBH, VHSH, PWK28, TMX30, Smartcarb 26-28)

The Polini membrane can do more than you would think.
A bigger carburettor than the most used 24mm Dell'Orto brings a considerable increase in performance. In order to use the larger cross section, this 30mm intake is needed.

Remove the original connection piece and replace it with this one.
30mm cross section are just right for e.g. 27 or 30 Mikuni TMX.
The carburettor sits as usual in the frame.

Scope of delivery: exchange suction cup with 30mm cross section suitable for V50 or Primavera frame, without Polini diaphragm.

Best is to order the suitable carburettor rubber (34mm) at the same time.
