Bike year & model = 2005 250 EC
Temperature (degF) = 5-25 'C
Elevation (feet) = sealevel + 1000ft
Main jet = 180
Pilot jet = 42
Needle & notch = DDK - 3.
Air screw setting = 2.25
Throttle valve/slide = stock #7
Way way way better than std NE1f, Crisp and strong throughout. Fuel economy is excellent - way better than it was. A really good and cheap improvement (about ?6 + postage for the needle)
(Tried a 45 pilot but light throttle got sputtery and air screw was fully out - the 42 improved it.)
Was given and have just fitted a JD Blue ready to try next time out.....Thanks again go to Todd for this
