Special version of our diaphragm intake manifold for engines with the short inlet sealing surface like T5, PX80 etc.
See last picture for an explanation of the different inlet sealing surfaces.

The rotary vane control of the large frame Vespa models (starting with the VNA models around 1962) up to today’s PX is as clever as it is sophisticated.
On the 200cc engines, whose rotary vane is wider than that of the 125cc models, performance of over 30hp with a good power band is now regularly conjured up. We offer flow-optimized MRP rotary vane intake manifolds to match.

Whoever finds this too little power has to change to a diaphragm inlet. This allows the former rotary vane inlet to be enlarged without having to consider its sealing effect. The diaphragm integrated in the new inlet meets the gas control requirements. A carburettor with a cross section of more than 30mm can therefore be used sensibly.

The diaphragm intake manifolds manufactured by MRP in Germany are intended for use with the high performance diaphragm type of the Yamaha RD350LC YPVS. The nozzles are available with a stainless steel tube or a flat top part CNC machined from aluminium. The quality, fit and possible performance are worth every cent.
