These needle are from a set of used carbs off a '96 ultra. They appear to be made from tooling steel and have an extra e clip position. There are no numbers identifing them leading me to believe they are custom or a brand other than Mikuni. I don't no the history of the the donor sled, but the pilot bypass holes were drilled out with number 30 pilots and the needle jets are 247- p-4's. My thoughts are that the sled was at one time piped and had slp or psi custom needles. Ok now they question, if possible, how do you measure needles and would this help me figure out what they are or will it always be a mystery? Oh and the tips of the needles are much more narrow than stock dh8 needles.
