MRP reed valve intake manifold SHORTY for Vespa PX and T5 - CNC-milled for short sealing surface
Special version of our reed valve intake manifold for engines with the short intake sealing surface such as T5, PX80 etc. See last picture for an explanation of the different intake sealing surfaces.
The rotary valve control of the Largeframe Vespa models (starting from the VNA models around 1962) up to today's PX is as clever as it is well thought out. On the 200cc engines, whose rotary valve is wider than that of the 125cc models, performance of over 30 hp is now regularly conjured up with a good power band. We offer flow-optimized MRP rotary valve intake manifolds to match.
If this is not enough power for you, you will have to convert to a reed valve intake. This allows the former rotary slide valve inlet to be enlarged without having to take its sealing effect into account. The diaphragm integrated in the new intake manifold controls the throttle. A carburetor with a cross-section of over 30 mm can therefore be used.
The diaphragm intake manifolds manufactured by MRP in Germany are designed for use with the high-performance diaphragm type of the Yamaha RD350LC YPVS. The intake manifolds are available with a stainless steel tube or a flat top part CNC machined from aluminum. The quality, fit and possible performance are worth every penny.
A big plus point of the MRP connecting pieces is that they do not require an adapter plate or that the engine housing has to be welded on. Suitable diaphragms are available from BGM, V-Force or directly from Yamaha.
Note: Racing product without road approval. However, the intake can be registered with an individual TÜV approval.
