2011 EC300R
180m
42p
AS 2.25 out. Could go to a 40 pilot but I am lazy and it starts so easy. With the current settings it will load up if idling for very long
N3CH 3rd clip
200-800ft.
75-95* F
50/50 mix of 110 leaded fuel and 93 octane pump gas with Motul 800 at 50:1
I am running a House of Horsepower pipe and silencer and the rest of the bike is untouched. Jetting is near perfect. Nice and crisp right off idle then a nice hard hit then it just revs to the moon and back. Plug looks perfect too

40 pj

Ddk #3
#7 slide
Average temp. 22 C
average humidity 40%
Elevation 614 ft.
Will not idle(have tried other pj) , runs crisp no bogging I find the plug a lil on the white side gonna go half clip richer, seems lean at mid throttle and is flat on top ....want to try n3ej hard to get parts here....have tried n1eg my bike hates this needle with every possible configuration except slide change

Elevation (feet) = 1000
Main jet = 170
Pilot jet = 38
Leak Jet = 85
Needle & notch =NOZI # 2 (or maybe "N0 Z1", as it says in the Partlist for the EC 125)

Just bought a used EC 300 from 2011 in Germany. Compared to you others I do hava a really strange jetting. It sounds quite lean but actually still is too rich. However I did not think the preowner changed ist, so could it be the std EU setting? Can anyone explain?

Bike year & model = '01 EC 300
Temperature (degF) = 75-100 Fahrenheit
Elevation (feet) = 4,600-12,000 feet
Main jet = 175
Pilot jet = 42
Needle & notch = N3EW middle/3rd notch
Air screw setting = 2 1/2 turns out
Throttle valve/slide = #7
Results: A bit fat off bottom but still very responsive. Very aggressive acceleration. 42 pilot at this elevation seems to be too rich but necessary because of a slightly lean needle. I'm thinking about going to the N3EH which I skipped over to maybe get back to a leaner pilot.

Bike year & model = 2014 EC300R E-start
Carb: 38mm PWK ASII carb
Engine: Modified head running 1.3mm squish, 1 x .5mm base gasket. CR unknown, slightly higher then stock - approx 12.5:1.
Temperature (degC) = 5-10 degC
50% humidity
Elevation = 1100m.
Main jet = 175
Pilot jet = 42
Leak jet = 85
Needle & notch = N3EJ #2
Air screw setting = 1.4 turns out
Throttle valve/slide = 7 non-notched
Results:
Low idle, slightly rich as it was prone to stalling when idling. Wicking the throttle response was close to perfect.
Was borderline as it came onto the taper, rolling along fire trails and snapping the throttle didn't lift the front as it should and a slight hesitation was felt when pulling through the rev range at approx 1/4 throttle feels like it's falling slightly flat. It also had a habit of running on a bit coming into corners.
I rode here using N3CJ#3 last week, same temps but 95% humidity and the flat spot wasn't there, on that occasion though it felt slightly rich. Humidity makes a big difference....
Made plenty of torque I was torquing round the single today in third and most hills in second with moderate clutch slippage. It never boiled but in the slower tighter stuff it got hot.
Fuel use was 5.8l for 58k's = 10k's per Litre.
95% was single, most of that is tighter techy single with plenty of snotty climbs.
Edit: used this jetting again on a two day ride. Average temps were between 15 - 20deg C with approx humidity of 50%. Elevation was 1000m. The ride consisted of two loops approx 65k's in length, did both loops once each day, so twice each. Both loops were a mix of single and twin trail, majority being 2nd and 3rd gear single.
Jetting is good, nice and smooth with loads of torque right off the bottom, bit of a rich flat spot approx 1/4 throttle then a good strong top end.
The flat spot was more noticeable the warmer the day got, and I confirmed it was a rich condition by pulling the choke on which made it so much more worse. It doesn't bother me too much other then its right in the part of the throttle I use to do wheelies, so most of my wheelies were crap. No real change there. I'm tempted to drop the main one size as there is more over-rev to be had as well I think, that may clean up 1/4 throttle just enough to be nice.
Fuel use for the final loop was 5.8l for 67.5k's = 11.6k's per litre.
Overall fuel use was 22.5l for 260k's = 11.55 k's per litre.
Edit: December 2015 - 25degC, 80% humidity, 300m altitude.
Went for a very tight technical ride. Only 42ks long. Still really happy with the jetting. It was slightly rich off the bottom and prone to stalling when idling along down hills etc but still made good strong power everywhere. Fuel use was bang on 10k per litre. In lower humidity this jetting will be perfect.
Edit: Winter 2016 (between June and August) - Been for a few rides now with this jetting in temps around 15deg C with humidity around the 60-80% mark. All around 300 or so meters above sea level.
This jetting is perfect. Great smooth power and excellent economy. Finally I'm a gasser owner very happy with the jetting.

very smooth power,gives more flexibility/throttle control,smooths the hit,idles nice,starts easy,doesnt choke up when doodling.the NEDH cleans up the richer bottom end of the stock NOZH and feels more progressive,and takes steady part throttle openings better.great for technical tight riding

Hi,guys, is not the best place to ask this question but I don't want to start a nother topic,so my dilemma is: witch one of these needles N1EF and N2ZW are good to put on my bike ec300 09, for better bottom end power? Someone use N2ZW? And for pilot and main I think to start whit 40 and 172 . Tem. -4~5 degC ,elevation 300m-1300m.
Thanks.
Thanks.

S3 Head black insert, stock pipe, Q Stealth
VP110 Amsoil Dominator 50:1
Sea Level-1000ft
40 pilot
AS 1.5
N3CH 2nd clip
180 main
Bike runs nice and clean across the board. Tried a 175 main and it wouldn't even rev out. Guessing the N3CH likes a little bigger main since most everyone else runs a 175. This is also the exact same jetting I used on my 2011 300 with S3 head and HofHP pipe.

Bike year & model = 15 300r estart
Carb=AS1 (screw top)
Temperature = 15-30c
Elevation (feet) = sea level to 1000'
Main jet = 170
Pilot jet = 40
Needle & notch = NEDJ clip#2
Air screw setting = 2 Out
Throttle valve/slide = 7
Float height=18mm
Power Valve=2.2
Motul 800 57:1
So I'm getting near the end of the never ending Reno, might as well have rebuilt the whole house, so I decided to do a semi race, which meant I had to fiddle with the bike. I cut down the stock muffler to 300mm and it needed resetting, on the as1 you have to remove the float bowel to change the pj so I was lazy and went to the Suzuki needles, knowing they like a leaner pilot. started with the necj clip 2, was very revvy but a bit gutless, so went to the NEDJ clip 2 and happy, nice mono machine, sort of similar to the n3cj with full length pipe but better bottom end due to pipe and better top due to Suzuki pin prick last taper, overal happy, no idea on fuel consumption yet.
Edit: did the Stroud 6 hr, jetting was great, no stalls, ballsy 1 tank for 3 hrs ride time, ticked up steep sandy hills like a diesel landrover.
