Just in case you haven't found your answer, yet, I thought I'd reply.
the jet needles that GasGas put in the Keihin carbs were the "N1E" series.
The N1EC, N1ED, N1EE, and N1EF (progressively leaner as you go down the alphabet) were what came in the older models. Around 2005, we started seeing the N1EG jet needles.

In this series, I prefer the N1EG. When we started using that needle, we were finally able to get our bikes to idle without bottoming out the throttle stop screw. In my 2006 DE300, I ran it with the "Jesus clip" in the second groove from the top. (along with a 42 pilot and a 175 or 178 main, according to the temps outside).

I don't have a chart, so I'm not sure of the NBHK.

Matt,
Thanks again for posting the chart. It sure has come in handy.

Good Riding!
Jim
