Is the same as a JD needle (didn't specify what color). Once again the mechanic who worked on my bike said " the NCVQ needle is the same thing as the needle in the JD kit". Any knowledgeable people care to comment on that? I was running a OBELN, 168 main, 200 main air, 48 pilot, 100 pilot air. He said there should be noticeable improvement. Oh yeh also installed a Boyesen QS.
