I'm thinking of dropping my needle back to clip 2 once it cools off a bit and maybe trying a 172 main.

Also thanks for the added info Jeff. This thread is almost like a goldmine for 2010/2011 Jetting specs. Appears lots of people having success with these needles.

Is the n3eh richer than the n3ch or leaner? I was thinking it was richer but am not sure. That would make sense with the 38 pilot.

N3Ex is half a clip richer than N3Cx

N3EH #3 = N3CH #2.5

Sorry for asking this but can I post JD's needle graph comparison chart or do you consider it illegal or some how offensive ? I just wanted to show the differences between the needles we are talking about.

I have seen it posted on another forum before.

Dear Admin, may I have your opinion on this subject ?

i'm digging around trying to find some jetting info on my new 2010 300, and found this thread. i've got the same jetting as OP, and while i'm happy with how the bike runs here and now (60-ish degrees F, sea level), it's likely the only places i will be going from here will be hotter in temp, higher in altitude, or both.

the bike came with a CHN needle in the spares. does anyone have any time on this, or know how it relates to the N1EF that is on the bike (top clip, leanest)? i can always go with one of the N3## needles people have mentioned here since i bought the bike from our local ktm dealer, but was just wondering if anyone knew anything about the CHN needle - it doesn't show up on sudco charts or anywhere else that i've been looking, and my calipers have a dead battery...

I would like to know as well but I suspect it might well have something to do with the 115 main included with the spare jets?

Vindicator,

Posting a screen grab of the chart for information purposes is fine, I have it myself and its a great tool. The only thing that would not be cool is passing pirate copies of the sheet around on the forum, as its JDs property. Same thing with posting valving specs from a tuner who makes a living at it.
