Bike year & model = '08 EC250
Temperature (degF) = 50-65
Elevation (feet) = 0-700'
Main jet = 178
Pilot jet = 42
Needle & notch = N1EG #2
Air screw setting = 2

Results: I run DENICOL S2 @ 50:1 , no other engine mods. It idles nicely and pulls up front wheel in 2nd and 3rd when snapping the throttle. I'm still playing about with the settings just to increase low end response. I got a cck needle just to try it out.
