Diameter of the straight part of the needle.

We are now in winter, last week the temperatures were around 5?C. I decided to test the needle N3WD I received long ago. I used it with a Jet 48 pilot in the 3rd position. Did not like the result, he fumed like crazy, and a strong middle-high transition.

Another detail with needle is repeated the problem of inconsistent idle. Do not know the length of the straight part of this needle, it may be as short as OEM needles, causing problems already known.

You're using a large pilot jet for that needle. For your 250 you should be in the 42 range. That Kawasaki N3xx needle jet series transitions into the middle quicker and harder than the Suzuki NExx needles. They are not as smooth as the NExx needles.

Thanks for the info.

I am really in love with smooth transitions of NE needles (Suzuki). However I'm seeking some fuel economy, as currently with NECF needle can not more than 75/80 KM. Any suggestions for a smooth needle as NECF where get some extra economy?
