MORE VITAMINS FOR YOUR VESPA.
Finally an enhanced intake system for the original DELLORTO SI carburetors.
Polini has modified the original Vespa PX 125-150-200 and LML 2T system and has added an oversized intake trumpet that is fixed to the original carburetor.
It is conical in shape and provides an added gas acceleration effect, called Venturi*.
It has been designed to increase the air-gasoline flow rate in intake phase to obtain an increase in engine power. The intake trumpet is assembled directly to the original carburetor with a simple screw. This means that the distressing original internal filter that causes the filtration to clog must also be eliminated, giving extra breath to the engine.
The nozzle coupled to the new power filter is distinguished by increasing the air flow without creating turbulence, Designed for use in place of the original rubber tube that connects to the chassis. Supplied with a large O-ring to ensure a perfect seal during filtration.
TECHNICAL CHARACTERISTICS:
- For SI 24/24 E (P200E) or SI 20/20 E (PX125) carburetor
- Washable foam power filter
- CNC aluminum intake nozzle and trumpet
- Includes 140 high jet jet
*It consists of a phenomenon in which a fluid moving within a closed conduit decreases its pressure when the speed increases when passing through an area of smaller section. Under certain conditions, when the increase in velocity is very large, negative pressures are produced and then, if the end of another conduit is introduced at this point of the conduit, the fluid from this conduit is aspirated, which will mix with the one that circulates through the first duct. This effect is named after the Italian physicist Giovanni Battista Venturi.
