These Keihin jet needles are given part numbers according to their dimensions

The syntax is N427-90-(TAPER)(L1)(DIAMETER)-(CLIP POSITION)

For example N427-90-GTT would be a taper of 1°30', an L1 of 65.90mm and a diameter of 2.775mm

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.)
