EC250R 2012 high RPM issue

[blamir]

Hello gassers,

My jets was like this,

178 Main Jet
42 iddle jet
N1EF needle #2 from top
Mixture screw 3 turns out.
Sea level

Bike was working abit rich. i had a problem on high rews. Bike was not going up high rpms. So i changed the jets like this,

MJ: 172
IJ: 32
N1EF needle #2 from top
Air screw: 1 and half turns out
Wheather: 28C
Sea Level

Throttle response is perfect. It is not passing on top revs. It is more agressive . Medium rpms is really good. But low rpms are abit week. At 1st gear, bike is not revving high as in the past. It is suddenly accalareting after low rpms .

I see that no one use N1EF needle, is this so bad? I really wonder other needle settings but it is not easy to find any another needle in Turkey.

What is your offers for better jetting? What is the best N1EF combination?
Is there any online sites to order needles with cheap international shipping option?

With new plug, after 20 min riding, with new settings. MJ: 172, IJ: 32, N1EF needle #2 from top




Thanks
