The lack of a like function on this forum is disturbing.

in 1 year nobody has corrected this. jd needle cannot be 2.88mm it wouldn't even fit in the emulsion tube if it was
1174 needle is 2.74mm not 2.78mm, the clue is in the name lol
not only that you said the jd red and blue needle are the same diameter yet the straight diameter is the only difference,
974 views and nobody has said anything

Well, you could have corrected it a year ago! :mrgreen:

I couldn't correct it. I don't have the info myself as I have never purchased one.

I never liked the JD needles. CEK or DEK for me depending on the power delivery I’m after.

No fun like the fun of posting to a years old thread...but this thread DOES seem like a good place for this to be. Put. It is elsewhere on the forum, but with a title of 'JD needle specs', here it is again. Also note: This post has nothing to do with the actual 'specs' of the JD needles!

This from James:
The needles in the KDX jet kits are in the same range as CEK/DEK single taper needles, but ours are custom machined triple tapered needles. They are precision machined and give a more even flow of power than standard needles, but do not get excessively rich like N85D type needles. There are 2 needles in the kit, which span either side of CEK/DEK with slightly richer and slightly leaner straight diameters. The Blue marked needle is for lower elevations and cooler temperatures (richer), and the Red marked needle is leaner on the straight diameter for warmer conditions or slower paced riding, but not excessively. Yes, these are special needles, as I've spent years developing and refining the taper angles and lengths to make them perform in varied conditions without being as sensitive to changing weather and temperatures compared to stock needles. The needles will work well with the RB modified carburetors.

Perfect!
This is exactly what I was looking for. I was about to break out the mic and start measuring needles.

So I have all 4 needles.
JD Red and Blue, CEK and DEK.

Can you be more specific on which will gives YOU what?

Do you select one needle for my single track and swap it out if a hit an MX track?

Of course weather conditions will also play a factor.
But generally speaking. Which needle for what power?
And I am thinking different mods will also be a factor. So...

DEK on a #2 clip is my favorite all around setting.
