I have kind of worked out a break down of the OEM Needle codes.
N-X-Y-Z (N3EJ) (NEDW) (NOZI) (N1EF) N - OEM Needle identifier X - Taper profile Y - Clip position/length Z - Diameter The X/Y doesn't seem to share any common ground between needles. 3 seems to be yamahas 2 taper needle. E is suzi's 3 taper, O is ktms 3 taper, 1 is the stock GG needle also a 3 taper. I'm not sure if the tapers are the same between the NOZ/N1E. They do feel very similar. The Y part which indicates clip pos/length is also paired up with the taper profile (x) to form a needle with the same properties that allows for half clip adjustments. Exmaples N3Ex/N3Cx, NEDx/NECx. I have a feeling NOZx/N1Ex is the exception and are half clip different using the same taper. Z is the needle diameter of the straight section of the needle. It covers idle to 1/8-1/4 depending on the needles taper profile. Sizes range from: Nxxx needle diameters D=2.685mm E=2.695mm (JD Blue) F=2.705mm G= 2.715 H= 2.725 W/I=2.735 (JD Red) J= 2.745 K=2.755 |
