Reed valve 8.1-K12 for 100cc, for 8.1 “Fireblade” crankcase Piaggio and Minarelli versions

A 4-way bipetal, with 9-12 (or 12/12 to choice) weft carbon reeds, it is very generous in the dimensions calculated specifically for the combination of the 100cc 8.1 cylinder kit and carburettors with diffuser up to 39mm in diameter. It does not require a stopper of the petals, as the latter fit perfectly in the housing of the carter. The whole is aimed at reducing obstacles, increasing the speed of the fuel flow and producing the right pressure on the fiber petals.
