Main Jet Types Mikuni cc min Amal 1 The first number indicates the length of dimension a The 5 in the example stands for 50 mm and over but under 60 mm A four would mean from 40 up to 50 mm and so on 2 Each needle is tapered in two steps The first letter indicates the angle of the upper taper 6 the next letter shows the angle of taper a the lower taper The letter A 0 15 and feach successive letter is for an angle 15 minutes greater By calculating for the example then G 1 45 and L 3 00 3 This is the manufacturer lot number Lot No 3 in this case and will vary with the individual needle 4 The last number the second 3 in this example is not stamped on the needle This is the number of the standard groove in which the needle clip is fixed for that particular modci A 3 shows that the standard setting is in the third or middle groove Jet Needle d Jet Needle The jet needle has 5 grooves for adjustment cut in the upper portion and is tapered from approxi mately the middle of the needle to the lower end The top is fixed to the center of the throttle valve by the needle clip and the tapered end extends into the needle jet Fuel flows through the space between the needle jet and jet needle which space is unvarying until the throttle reaches the 1 4 open point At this time the tapered portion of the needle begins to move out of the jet and affect fuel flow as the opening enlarges It follows that taper wear and the position of the needle clip in the grooves also affect fuel flow rate If the needle clip is changed from the standard position to a lower groove the needle taper starts coming out of the jet sooner resulting in a richer mixture moving the clip higher produces a leaner mixture Each jet needle is designated with a number letter code the meaning of which is explained below Except for the last number 3 in this example this code is stamped on the needle directly below the 5 grooves Example 5GL3 3 Jet Needle IT e Needle Jet As explained earlier the needle jet works in conjunction with the jet needle to regulate fuel flow rate In the side of the needle jet there is an air bleed opening which brings in air measured by the air jet This air initiates the mixing and atomizing process inside the needle jet and mixing is augmented by a projection at the needle je outlet called the primary choke The letter number code stamped on the je indicates jet inside diameter A 0 2 code fo example means the inside diameter of the needle jet is 2 61 mm Needle Jet Tf Primary Choke
