Bike year & model = 2008 Gas Gas DE 300
Temperature (degF) = 45-60
Elevation (feet) = 250'- 5000'
Main jet = 178
Pilot jet = 35
Needle & notch = N1EF 2nd position
Air screw setting = 1 to 2 turns out depending on temp and elevation
Throttle valve/slide = #7
Results: Crisp clean response. I run Chevron Supreme and Golden Spectro at 50:1 and my Irridium BR8EIX Spark Plug burns a beautiful tan just like that perfectly cooked camp fire marshmallow.
