EC 250 2008 jetting problem
Hi guys.. I need some help... I try to tune the jetting.. I Have slide #7
Pilot Jet #45
Main Jet #175
Needle N1EG on the leanest position
when I try to set idle I need to have Idle screw totally in and air screw just half a turn from fully closed. If I turn airscrew even 1/4 turn out idle starts to stick so it looks like it is lean. But on the other hand I have oil coming out from exhaust and my powervalve stick closed after riding a while in low RPM. I need to pull WOT to clean it and than it runs good, but lastly I tried to clean it with WOT and it fouled the plug and I needed to change it. Old plug has black electrode but the rest of plug looks totally clean. Can you help me with this? I have already received NEDW needle I ordered so I will try it today
