thanks.

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.

This is the jetting I ran on my 2011 300 Race, but I think it work better on this bike.

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.

Have updated my settings now...

Needle e3eh 2and from top clip 150 M 38 P with 80/1 gas mix runs fast high and low great botton end

[n_green]

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?
