Your reed valve block is the connection between manifold and motor block where intake is controlled. To give you an idea of how it works, picture this: when the piston moves up, a vacuum develops in the crankshaft, causing the reed flaps to open, allowing fuel to flow through the valve block. As soon as the piston moves down, pressure builds, pre-compressing the fuel mix. Now, the flaps close again, hindering back flow of fuel. A racing reed valve block is one of the absolute basics of motor tuning - giving you optimized fuel flow.
The POLINI reed valve block distinguishes itself through following features: larger induction diameter, improved . ow, improved cylinder . ling, carbon . aps and rubber gaskets.
