The \u003cstrong\u003eversion 3 includes\u003c\/strong\u003e many changes compared to the previous one.\u003c\/p\u003e\n\u003cp\u003eThis evo 3 model is a kit made of aluminium treated with \u003cstrong\u003ehigh-end nykasil\u003c\/strong\u003e, its diameter is \u003cstrong\u003eØ47.6mm\u003c\/strong\u003e which offers a real displacement of about 70cc.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cdiv\u003eThe diagrams around \u003cstrong\u003e190\/130\u003c\/strong\u003e are well designed \u003cstrong\u003efor circuit use\u003c\/strong\u003e, balancing peak and torque! The piston is \u003cstrong\u003esingle ring\u003c\/strong\u003e to allow for the highest speeds, this ring is \u003cstrong\u003every thin\u003c\/strong\u003e (0.80 mm), hard chromed and domed so that friction is further reduced. This piston is treated with a high \u003cstrong\u003esilicon content\u003c\/strong\u003e which gives it that matte appearance.\u003c\/div\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003eThe most \u003cstrong\u003emodified\u003c\/strong\u003e part is the exhaust outlet of the cylinder, which now comes \u003cstrong\u003epartitioned in the form of a T-Port\u003c\/strong\u003e. Compared to the Evolution 2, it is noticeable that the two additional outlets have been replaced.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eexhaust\u003c\/strong\u003e outlet is \u003cstrong\u003epartitioned in the form of a T-Port\u003c\/strong\u003e (rectangular), which may seem quite surprising but \u003cstrong\u003egreatly improves the efficiency\u003c\/strong\u003e of the horizontal exhaust. The \u003cstrong\u003eintake\u003c\/strong\u003e is carried out through \u003cstrong\u003e6 transfers\u003c\/strong\u003e, 2 rear, 4 lateral, which are also very well designed as they pass under the exhaust, and to achieve maximum performance it is \u003cstrong\u003erecommended to use a 24mm to 28mm carburettor\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cdiv\u003eThe cylinder head is made up of \u003cstrong\u003etwo pieces\u003c\/strong\u003e, head and insert, to achieve the \u003cstrong\u003ebest possible cooling\u003c\/strong\u003e.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cp\u003eWith these \u003cstrong\u003ecompetition kits\u003c\/strong\u003e, a set of base gaskets of different thicknesses is supplied to set \u003cstrong\u003eyour squish\u003c\/strong\u003e.
