EC125 2007 jetting
 

Hi, does anyone knows any base jetting for an EC125 2007?

have you checked the jetting database Sticky?

I did not see a 125 listed in Matt R's sticky of the jetting database.

With the '01 XC125 we had at the shop:

AS1 Keihin
N1EF needle with the clip in the third position
40 pilot
180 main jet

This was before I learned a lot of the info about the jetting that I now know, but it worked pretty well.

The bike was super sensitive about the jet needle and which groove the clip was in. Just a shade too lean and it had no bottom end power. One groove on the needle made all the difference when riding the bike in the mountains. It went from a nightmare ride to a rocketship with good low/mid-range torque.

.

Thanks for the replies! Finally, i contacted local GG and they suggested me as stock jetting:

Needle: NOZI (position 3)
Main Jet:180
Pilot: 45
Air Screw: 1.5 turn
Throttle Valve: 7

EC 125 2007 wears a Keihin 38 PWK.

Large squish and low compression make them difficult to jet.
