Intake manifold - for reed valve -POLINI reed valve X360- Vespa PX80, PX125, PX150, T5, Cosa 125-200 - CS=Ø34mm (carburetors Ø28-30mm - PHBH, VHSH, PWK28, TMX30, Smartcarb 26-28)

Suitable for all motor housing variants of large frame motors such as the Vespa Sprint, Rally, PX, Cosa.
Has a sprue and thus a reduced passage to fit also on engine housings with small sealing surface (T5 and PX80-150 with less than 60 millimeters sealing surface, measured between the holes for the carburetor mounting bolts).

The newly added sealing surface inside the connecting piece forms a strong flow edge, on housings with long sealing surface we recommend to mill the connecting piece inside. Alternatively, we recommend the intake connection EVO1 from MMW.

As with all conversions to a diaphragm-controlled inlet, the original rotary vane control via crank cheek is not required. Therefore the engine housing can and should be milled (for an optimal performance increase). Optionally a crankshaft for diaphragm inlet is recommended for a further increase of the engine performance.

• Intake rubber infinitely variable 360° adjustable
• Good insulation of the carburettor against the engine heat
• Small installation height
• Gummed, self-sealing diaphragm body with 0.3mm carbon platelets
• cover of the oil pump hole
• Fits motor housing with short or long sealing surface

Attention: For assembly it is necessary to screw two brass threaded bushes (enclosed) into the holes of the carburettor fixing screws of the engine housing. The connecting piece itself is fixed to the engine housing with two M5 hexagon socket screws.
