These Keihin jet needles are given part numbers according to their dimensions
The syntax is N427-5-(TAPER)(L1)(DIAMETER)-(CLIP POSITION)
For example N427-5-AHR would be a taper of 1°35′, an L1 of 24.25mm and a diameter of 2.750mm
Clip positions are not required for ordering but for the sake of notation, 1 is the top clip position. (Near the blunt end of the needle.)
