Bike year & model = 2003 EC200
Temperature (degF) = 68 - 100 Elevation (feet) = 1300 – 2500 ( roughly varying ) Main jet = 178 Pilot jet = 48 Needle & notch = N3HJ - 2 Air screw setting = 2 3/4 Throttle valve/slide = 5 Results: I use this setting all year round. I have found that it is very smooth from bottom to top. Air screw was 3 ¼, but wouldn’t idle when warm, now at 2 3/4. I’m considering moving needle to middle notch for better bottom end. Am using Motul 800 mixed at 50:1.

2001 ec-300 with motocross ign and RB style head mod
Temperature (degF) = 40-90 Elevation (feet) = 2200- 5800 Main jet = 165 messico & doma pipe, 170 fmf pipe Pilot jet = 35 Needle & notch = Kawi N3YF #3 notch Air screw setting = .75 turn out Throttle valve/slide = #9 Results. Very crisp throughout the rpm range, pulls hard with instant throttle response and good high rpm power , Caveat , would not ride in sand with this small a main jet, 10 minute road section at W.O.T. with no problems and no overheating Last edited by widebear; 05-18-2008 at 10:20 PM. |

Bike year & model = 2004 DE250
Temperature (degF) = 50 - 70 degF Elevation (feet) = Sea level to 1000 ft Main jet = 180 Pilot jet = 45 Needle & notch = LTR -0 #3 Air screw setting = 1-1.5 turns out Throttle valve/slide = #7 Results: Much cleaner jetting that my prior post. Bike runs strong and smooth in conjunction w/ .45mm base gasket on my cylinder.

GG27 revised settings
Bike year & model =EC 250 2008
Temperature (degF) =60 TO 85 Elevation (feet) =0 TO 1000 Main jet =182 Pilot jet =45 Needle & notch =LTR - 0 #3 Air screw setting =1 to 1 1/2 Throttle valve/slide =#8 Results:After changing slide to a #8 I raised the pilot from a 42 to a 45 and bike runs strong throughout with no bogging at all. I changed silencer from the standard banana to the MC and hits stronger with better throttle response from mid to top, signs off a little quicker. Now I can tell the difference with the dual map switch. I prefer the standard long silencer, it gives a broader spread for overall use, MC silencer is good for the motocross track or rain setting for tight woods.

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.

Bike year & model = 2005 DE250 (11oz FWWeight)
Stock reeds. LTR needle with clip on position 2. LTR PV cover. Stock slide. Winter in Phoenix: Temperature (degF) = 40 - 80 Elevation (feet) = 1100 – 2500 Main jet = 178 Pilot jet = 45 Needle & notch = LTR - 2 Air screw setting = 2 1/2 Throttle valve/slide = stock Summer in Phoenix: Temperature (degF) = 80 - 110 Elevation (feet) = 1100 – 2500 Main jet = 172 Pilot jet = 42 Air screw setting = 1 1/2 Summer in Flagstaff: Temperature (degF) = 75 - 85 Elevation (feet) = 7,000 – 9500 Main jet = 165 (I gave the 168 a try -- almost but not quite lean enough -- a little burble on top. 165 did the trick and was particularly crisp if I dropped the needle to the first clip). Pilot jet = 40 Air screw setting = 2 1/2 Last edited by AZRickD; 10-04-2009 at 08:50 PM. |
