177 VALVE INTAKE TRANSFER
The new kit Pinasco 177 VIT (Valve Intake Transfer) for Vespa PX, with valve intake on the cylinder, is a revolution in the world of Vespa tuning kits because of the brave selection of its components. The cylinder has a new direct valve intake on the cylinder, Pinasco has been the first company that made a valve intake for Vespa like this in the eighties. Pinasco engineers took back that old project converting it to technology and components of today.
The cylinder is made of a special cast iron and it is shaped for optimal performance on all kind of way from the winding mountain roads to the straight of the motorways. This is possible because of the specific configuration of the compression and exhaust strokes. The valve pack is made of aluminum, Viton treated inside to guarantee a very good fluid dynamics. The reeds are in a very high quality carbon.
A new kind of carburetor is included in the kit; it is a depression 27/32 with integrated fuel pump to guarantee the correct quantity of fuel in any driving avoiding vacuum of mixture that, very often, are cause of seize up of the engines. Another big advantage of this carburetor is that it is without jets air/mixtures and it is possible to set the carburetion just screwing and unscrewing two screws of regulation of idle speed. Another very important feature of the kit is that during the installation it is not anymore needed to modify the turning valve like in the past because special plaque to seal it is included.
To come back to the original configuration of the engine it is enough just to remove the plaque and put the original cylinder and carburetor in their original position. The engine will be exactly like before.
