I've been doing a lot of reading on here about which needles are recommended. As elevations are a big factor, it's hard to narrow it down. I'm riding at sea level. 2012 EC300 Race model. Came with a 38p, 175 main, and JD red in clip 2. Plug looks a little too light. I put a 40p and a 180 main in. No noticeable difference. I moved the needle to position 3 and it burbled, so back to clip 2. For my riding, I think that the 07 RM needles are the ones I want. Which ones should I get though? I'm looking for something fairly rich as I ride at sea level. Thanx.

I just ordered the NEDW and a NEDK. Hopefully they put me in a good spot. Plug looks nicely tanned, except around the outer ring right before the threads. That apparently means that it's still a bit lean and I can occasionally hear a lean knock. I also ordered a 42 and a 45 pilot. The 45 is probably a bit too rich, but I'm not sure what I'll be getting into with these different needles. That red JD needle that's currently in there looks like a pencil. Not much of a taper.

Anyone ever try a N1JK needle? Just put one in and it was pretty dead down bottom, but exploded power all through the mids and highs. Like, wheelies in 6 gear with little effort! I think this needle may be out of a KX?

Are these needles ideal for sea level?

You are concerned of being lean and have bought a couple sizes larger on the pilot, but then purchases (and tried) a K diameter needle which is about 3 steps leaner than the JD red in the off idle to 1/8th throttle range.
Based on what you've been saying I would be going for something like an NECW and an NEDW. One size leaner in diameter than the JD, but gives you half clip variation between needles to fine tune the clip position. Reading plugs is anyones guess with current variations in both fuels and lubricants. Adding to that just looking at a plug in general won't tell you much. You need to do plug chops at certain throttle positions. For a crude test, put an old plug in that's half fouled up and take it for a run. If it comes back with white ash on it you know you're lean - but realistically you should be able to feel this and have other symptoms show first. |

I did order a NEDW, so I'll give that a go. I also ordered a NEDK. Which one would be richer of those 2? I've been pretty good at jetting my other smokers before with different mains and pilots, but never played with switching needles before. Thanx. |

NEDW is fine for sea level. Probably in clip 2
