Bike year & model = 2011 EC300E fitted with 36mm carb and reed block spacer and fitted with modified head (squish - 1.28mm, compression ratio - 12.7:1)
Temperature (degC) = 27 degC,
30%? humidity
Elevation (feet) = 1000f, or 200 -500m
Main jet = 168
Pilot jet = 40
Needle & notch =JD Red #3
Air screw setting = 1.25 turns out
Throttle valve/slide = 6.5 notched

Results:
Very snappy power. Crisp throughout rev range. Torque suffers down low and as a result the clutch needs to be abused a lot more down low in the revs to keep it alive. More prone to stalling compared with the blue needle.
I also tried a 42 pilot with air screw at 2 turns out and the torque and resistance to stalling improved, though still required a lot of use of the clutch and was unimpressive when compared to the blue needle.
Through the middle and top it screams, may be slightly lean on top which moving the needle to clip #4 would probably fix.
With the 42 pilot it upset the middle a little bit in that the power was doughy until about 1/3 throttle then it cleared its throat and screamed again.

In short this isn't a needle I'd use for technical riding or singletrack, it's not smooth enough and too much hard work getting up snotty technical hills the blue needle would simply walk up.

Fuel economy averaged about 1l per 10k. Done several rides and hit 75k's without needing reserve.
