Rode for the 2nd time with the NEDW needle, with today being the hardest I've rode with it.
Off closed throttle seemed a bit soft. At 1/2 throttle on up,it ran like a scalded ape.

For wet slippery conditions, this needle would be perfect.
May go with a leaner off idle needle.

I hear you GGM. What pilot and clip position did you end up settling with? I have found this needle very soft in the 1/4 to 1/2 throttle range. Not so much soft but just smooth. It still pulls and will lug its way up the steepest of hills. It just has no hit or snap until you get up higher into the revs.

Its definately boring, but works well when riding. You have a torquey predictable beast in the bottom end and a ball tearer up top.

I tried the clip in the #2 position, but the rpm was too slow to return to idle.

People mess with power valve springs etc. to change the throttle response.
A simple needle change is all you need.
Traction was excellent today, so the needle was too "soft" for me.

Fair call I am comparing your 250 to my experiences on a 300 too. So obviously there will be some big differences in off idle grunt with that alone. Keep us posted with your other updates and changes you make.

Also what was your previous specs?

Not so sure about this. I took all free play out of actuator plate (about 4-5 mm) and test rode today. A completely different bike, no lag - was crisp and responsive all through range, unbelievable!!!!! Only change to needle (N3EJ) was dropping to clip 3. I also had a fresh top end and high comp head so all these would have helped.

I will try the NEDW next weekend to see what improvements (if any) it will make.

My experience with the NEDW needle is that is softened the power below 1/2 throttle.

I agree. What needle are you comparing it to? N3? N1?

[gasgasman]

CEK-3.
The AirStriker II carb must be really sensitive to what needle you use.
