Bike year & model = EC300 '07
Temperature (degF) = 70
Elevation (feet) = 50 / about 1010mbar / 70% rel. humidity
Main jet = 175
Pilot jet = 42
Needle & notch = LTR #3
Air screw setting = 1.5 turns
Throttle valve/slide = #7
FMF Gnarly, otherwise stock.
Results: Very happy. Idles good, clean & strong through whole range, average about 4 liters/hour at (my slow) race pace, no spooge, black threads on sparky but tan electrode.
Peculiar: After starting cold with shortest possible use of choke, I allways need to run it hard through the gears to clear it out. After that it can run at really slow speed for a long while without loading up.
