Set of 10 EVOK cycler jets maximum and minimum DELL'ORTO 5 mm from 75 78 80 82 85 88 90 92 95 98 for DELLORTO, KEIHIN and MIKUNI carburetors type 01486

The new series of jets for DELLORTO, KEIHIN and MIKUNI carburetors. The importance and characteristic of the new production of main jets is the high manufacturing precision and the control carried out in a millesimal way on the measurement of the passage hole in order to guarantee a correct modification to the carburetion. The main jet acts on the carburetion mainly for the last three quarters of the throttle opening, but still makes its influences felt even if in a less marked way starting from the medium openings. Modifications to the carburetion: Increasing the size of the jet enriches (fattens) the carburetion, increasing the quantity of petrol sucked by the engine. Reducing the size of the jet impoverishes (leans) the carburetion, decreasing the quantity of petrol sucked by the engine. An increase in the ambient temperature or an increase in altitude above sea level causes a lower density of the air causing a richness of the carburetion. Incorrect carburetion adjustment with excessive leanness (reduction of the jet size) causes the engine to overheat and eventually seize. Incorrect carburetion adjustment with excessive richness (increase of the jet size) reduces performance by increasing fuel consumption and causing fouling of the spark plug.
