Jetting for 2011 EC250 UK
Looking for a starting point for jetting on a 2011 ec250
38mm AS2 carb. I'm unsure on current jetting specs. Typical UK weather 6?c to 14?c. 0- 1000ft Thanks in advance. Looking for needle recommendation. Tight wooded trails with the a few hillclimbs. Thanks |
Hi Quigs,
have you had a look at the jetting thread? I am sure you will find useful information there as most members post their personal settings there. Good Luck Steve |
Hi Steve.
I been having a good look through the jetting threads etc. Looks like the NEDW suzuki needle could be a good starting point. Also recommended by jakobi. |
Just checked my specs now and 're as follow.
PJ 40 AS 3/4 OUT NEEDLE, N1EF 2ND CLIP MJ 178 |
Someone just posted a similar question, see it here...

Thanks Dave.
Ordered the NEDW now |
Got the NEDW needle.
Thinking of starting at 42 pj, needle position 3, and a 178 mj |

If you find clip 3 too rich,clip 2 too thin...options...
Necw is same taper,same diam,half clip pos leaner Necw#3 = Nedw#2.5 Was useful for the 200(Nech #3)but most 250s seem happy with Nedw#2 |

Thanks for all the input,
Currently now on. 40 pj NEDW #3 172 mj 1.5 OUT on the AS Going to just try raising the needle to #4 so it feels rich then go #3 and #2 Just so I can feel the difference. Still new to jetting so just want to feel and hear the difference |
Went out on bike over the weekend but getting a bit of spluttering when trying to accelerate. Might need to try needle in clip position 2 ??

As per post #9, you may need to be between clip positions 2 and 3 to hit the sweet spot that a lot of people report using NECW @ clip 3.
You can do that by using a fine shim under the needle rather than buying an NECW. I got one from a local model shop that did the trick but it's very fine tuning for a bike engine in typical unpredictable UK weather. |
