NECW#3 would be a half clip richer than NEDW#2. Anyways start another thread if you want to discuss it further. I don't want to ruin the database.

2012 300
Elevation: 0-1000m
Weather: 25-30 celcius
Humidity: 60-100%
Location: Queensland Australia
Main: 178
Pilot: 42 but going back to 40
Needle: N3CJ clip#3
Float level: 1-2mm lower than standard
Feel: It has plenty of lugging power but needs a 40p to clean up the bottom, There is a fairly strong surge into WOT which will make you
At the end of the day it is my kind of setup for fun factor but if you are an endurance racer doing solid stints then you may want a more smooth transition but if its a weekend fun factor then try this!!
Thanks jakobi for the advice prior to setup.

2012 Ec 300
Elevation: 0 - 200m
Weather: 15 - 35 deg celcius
Humidity: 20 -40% at a guess.
Location: Adelaide, South Australia
Main: 178 -180(180 now, going back to 178) DONE
Needle: N3EH, clip #2
Pilot : 38( going back to 40)DONE
Air screw: 1.5 turns out NOW 2-2.5 turns out
Float: 1-2mm lower than standard.
With the current set up the transition is nice( not harsh at all).
Plenty of power right through the range.
The dropping of the main from a 180 to a 178 will clean the whole range up I reckon and combined with the 40 pilot should be perfect.
Once again , thanks to Jake for the lend of the needles and the advice.
Good on ya mate.
Very easy to ride as minimal hit , just good solid power which builds and builds right to the top end.
Have now made the final changes and am very happy. Very clean , strong power all the way from bottom revs to top.Here is the plug after a WOT plug chop:

Ec 300 - 2012
Elevation: 300 - 1000m
Weather: 25 - 30 deg celcius
Location: Romania
The standard settings: N1EF #3, 172 with 42 and air 1,5 open was ok at the begining, during the winter time but with the spring time and temp over 20 deg cels started to go bad, too rich and a lot of black thin oil on the silencer exit after a day riding
I saw here and i tried also: 42p N3CJ#3 175m. a lot of power (for me is ok, becouse I preffer hard/extreme enduro ride) but also quite a lot of unburned oil at the silancer exit and the main problem: don't start with cold motor, or start very, very hard
so, now i have what manual says for this temp and altit:
N1EF #3, 168 with 35, air 2 open
run better, no dead point in power delivery, not so much smoking but still some unburned oil at the silancer exit. what i don't like now is the power. power valve is coming in to quick and the engine is very nervous, to aggressive and don't have the same torque
I will continue to look for the best setting
I hope eventually to say like the guy before me. but right now I don't have N3EH right now !
and I also saw a lot of good things about CCK needle, but I found none so far in Romania, is it like a N3** or may be even compared with some needle from N series?
wish you only best ride

StefanRO. Start a thread in the jetting section and you'll get pleanty help. Also try and work with what you have. If the bike is hard to start cold, make sure you are using choke and keep it on for a bit until the bike comes to temp. Try closing the air screw in some to see if it helps by making it a bit richer. You may need to go up a size on the pilot. Also try lifting the needle a clip position to clean up the mid range and reduce the spooge a bit. In my 300 at same elevations, temps, and with high humidity I ran 42 N3CJ#2 175/172. It was probably a touch leaner than most would be comfortable with but ran super clean and got great fuel economy.

Thanks for posting Haydn, I'm in Louisiana so this should work for me too.

I'd recommend the N3CJ over the N3CH for a 300. Its just a bit leaner at 1/8th throttle which cleans up the lower throttle openings.

2011 EC300 Jetting 4000/13000 Ft 80/1

Needle e3eh 2and from top clip 150 M 38 P with 80/1 gas mix runs fast high and low great botton end
Bike year & model = 2011 EC300E fitted with 36mm carb and reed block spacer
Temperature (degF) = 50 - 60 F, 50% humidity?
Elevation (feet) = 3000f, or 900-1100m
Main jet = 178
Pilot jet = 38
Needle & notch =N1EG 1st clip from the top
Air screw setting = 2.25 turns out
Throttle valve/slide = 6.5 notched
Results:
This was in the bike when I got it second hand. The previous owner said he had it re jetted by his local bike mechanic.
The bike seems a bit doughy right off idle before it explodes through the mid range and then dies up the top. Im not sure if it's slightly lean or rich on the pilot though I'm thinking slightly rich as it seems to clear and the pull hard through the mid range. Playing with the air screw there isn't a great deal of difference between .5 turns and 2.5 turns out. Mid range seems really good and I'm happy with it. There is no overrev on this bike. It is way too rich on the main. I can feel it flood and it loses all power and sputters.
It also appears to be bad on fuel economy, after a 60k ride 50/50 fire trail/single track lug it had used roughly 7L of fuel.
I plan on playing with the main and needle. I've ordered some NECW, NEDW, NECJ, NEDJ Suzuki needles, hopefully this wil clear up bottom end without sacrificing the mid range. I'm wondering though if the slide has something to do with the bottom end richness?
I'll also have to get some smaller mains as all the spares that came with the bike are all in the 170's and I'd think that's too big for a 36mm carb?

Ec 200 2001
i got a CCL needle with clip pos 2 (from top) 45 PJ and 180 MJ.
temp 5-20 Celcius and 0-100 m elevation (sealevel, belgium)
idles pretty wel and runs very smooth, very well controlable.
starts 1st kick when warm, cold takes max 3 kicks.
absolutely pleased with this setup.
no head mods have been done (yet) just might use a thinner base gasket to up compression a bit next time if i shoud (ever) swop piston
EDIT : so now i've put a new piston in it ,and left the base gasket OUT (more compression, better squish from 1.82mm to 1.32), i used permatex (liquid gasket).
after some rides (0-5 degr Celcius) it felt too rich off idle, so i swapped the 45PJ for a 42 and that seemed to make a huge difference. much more crisp engine response thrueout the revs!
RE-EDIT : since it got a little warmer, about 10-15 deg Celcius, i put an even smaller PJ in, went to 40.
yet even better idling.
just have quite some spooge, does this mean i'm either running too rich on the main (180) or i'm not revving it enough (no need to for what i do).
might try 178 MJ... any thoughts on the spooge?

Good throttle response throughout rev range. Smooth transition between circuits. Pulls hard off the bottom through mid range to top end. Slight knock/pinging and feels slightly lean around 1/8 to 1/4 throttle. Slightly snappy right off the bottom too and on occasion would hang slightly just above idle for a second or two.

Air screw setting = 2.25 turns out
Throttle valve/slide = 6.5 notched
Results:
Great torque off the bottom. Pulls from right down low, smooth transition through all circuits. Burbles ever so slightly just off idle. Slightly lean? At approx 1/4 throttle not too noticeable. Pulled hard from bottom through mid but seemed to die up top, would rev out but not make power. May try going one step leaner on the pilot and also one step leaner on the main.
Edit:
I went one step leaner (38) on the pilot, didn't like it, lost a lot of the torque and had trouble getting it to idle nicely so I've gone back to the 40.
Went one step leaner (170), has made a noticeable improvement to the top end though I still think I could go one step leaner again. I'll leave it alone for now though as I'm hapy enough with it for now.
Edit again:
On the weekends ride (same altitude though about 5 deg / 10 f cooler) was hitting reserve at 70k's using jetting of 40p, JD Blue #3, 170m. Also the slightly lean feeling I believed I had at 1/4 was actually rich. Now I've installed the Motion Pro T3 throttle cable I dropped the pilot to a 38 and wound the as in to between 1.5 and 2 turns out, dropped to a 168 main. Made no noticeable difference to the bottom, as in still an awesome torquey unstallable tractor but the mid and top end did improve noticeably. I then got 75k's to reserve.
Still felt slightly rich so I raised the clip to #2. Really really happy with this jetting now, I've finally woken the top end up and improved the mid range in the process, can now loft the front wheel as high as I want from any throttle position in 3rd gear and the power delivery is nice and linear without any burbling, surging, knocking etc. Occasional pipe bang once in a blue moon on steep down hills as the bike comes back down to idle speed in 1st gear, but only once in a blue moon.

With this jetting my bike is very, very crisp, much more powerful than with the stock needles, perhaps to much for some people but if you are a rider with good abilities then this is your ideal setting. I don't know the gas mileage with this setting but I will be testing it in my next ride.

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.

Results:
This was my first run using the oval bore carb. I went 1 step richer on the main however left my 'preferred' JD Blue jetting the same apart from that.
All I can say is wow, the carb has really woken the motor up, it has even more torque off the bottom now, and I found myself lugging 1 gear higher most of the day, even attempting and most of the time making steep 1st gear hills in 2nd. This is with 13/48 gearing. It refused to stall and I rarely had to use/abuse the clutch at all.
I feel this jetting is rich throughout and may be slightly on the rich side at WOT. From off idle the bike pulled hard regardless of gear, it became doughy through the mid but still pulled harder then it ever has before and then went ballistic through the top end. It had to wind itself up though it wasn't crisp and I found just snapping the throttle open from low revs wouldn't bring it into band or loft the front.
I took a spare 1.5l of fuel with me today, glad I did. I used 10.6l in 80k's
Bearing in mind I was at 1200m asl most of the day so it would have been running rich anyway with my old settings. I'll try leaning off the main to a 168 and then play with the clip position to fine tune. Hopefully that will get me back into decent economy territory.

I took a spare 1.5l of fuel with me today, glad I did. I used 10.6l in 80k's
Bearing in mind I was at 1200m asl most of the day so it would have been running rich anyway with my old settings. I'll try leaning off the main to a 168 and then play with the clip position to fine tune. Hopefully that will get me back into decent economy territory.

Bike year & model = 2011 EC300 Six Days
Temperature (degF) = 65
Elevation (feet) = 500
Main jet = 172
Pilot jet = 40
Needle & notch = NEDW 1
Air screw setting = 2.0
Throttle valve/slide = 6.5
Results: Very clean and smooth. No MX type mid hit. Very smooth = lots of traction.

Bike year & model =2001 ec300 new pwk 38 carb
Temperature (degF) =50 - 90
Elevation (feet) =1500' - 4500'
Main jet =168
Pilot jet =38
Needle & notch =cck #3
Air screw setting =1 + 1/8
Throttle valve/slide =8mm slide cut
Results:A used bike new to me. After much jetting frustration, I concluded that the needle jet was worn out.
The only part in the carb that wears out and you can't replace it. New carb!
I'm looking for best mixture delivery between 0 and 3/8 throttle. With this receipe,
the power generated as soon as you crack the throttle off its stop, is awsome.
Tire shredding power from sub-idle in any gear, with smooth hard pull to good
over rev. The cck needle didn't work well with the stock 7mm slide, but nothing i tried
did. Idle, very sensitive to temp and altitude changes. Usually 3lt fuel consumption
for an average 2 1/2 hr technical ride. This is a work in progress, but theses results
seem worth reporting. Any tips, hints, or critizisims, will be welcome.
