I posed this question in the "What did you do to your WR today" thread, but I wanted to get some opinions before I return the JD Jetting kit I've got to RMATV today at lunch. I've got my carb set up pretty darn well right now - it starts/runs great in the summer and after throwing in the 170 main and tweaking the fuel screw, it starts/runs great in the winter also. Straight from the other thread: I'm at about 4000' MSL and the temps when I ride right now are around 50 deg F. My current set up is: Main: 170 Pilot: 48 (I think...I just pulled it to check when I re-jetted and wrote it down at home) Leak: 45 (and I have my accelerator pump linkage safety wired together) PAJ: stock Starter: stock Fuel screw: 1.75 or 2 turns, I forget (tweaked it with the tachometer) Needle: GYTR, third groove from the top So my real question is: are the JD needles really worth holding onto this jet kit? I didn't realize how many extra jets and parts I had laying around when I ordered it, and all I could use would be their red and blue needles. Not to mention I was pretty underwhelmed with what you get for $75. The GYTR needle as set seems to do great and I have no dead spots anywhere. This would seem to answer my question, but just curious if anyone thinks the JD needles are magic and would be worth trying for $75.
