2010 EC300 Factory Jetting Specs - WTF?

[iancp5]

Try a 38 pilot - thought that was the recommended for a 300 at low altitude with an N1EF.
Also worth trying the CCK needle if you want strong linear pull without a specific hit anywhere.

[Klausen]

My GG EC 300 had no real power and blubbers in the midrange.

My old specs
the f... new carburator:
slide #7
main:180
idle: 42
idle screw: 1 1/2
needle: N1EF #1 from top
Temp: 5-12?C or 41-53?F
altitude: 120m
original pipe and turbinecore silencer

The N1EF is to rich in every position.

Now I ordered only the CCK and DDK needle
and replace only the CCK needle #3 from top
Temp: 5?C or 41?F

After more testing the bike got no idle (pulling over) and very bad throttle response.
The DDK CCK don't work for the PWK 38 new model!!!!

[Jakobi]

Any updates?

I just ordered a few more needles to try out

N3CH and N3EJ..

Also has been noted in another thread that the new Air Striker II carbs with the metal cap that is bolted/screwed on generally requires much leaner jetting and possibly is a 36mm carb as opposed to 38mm.

If everyone could advise which model carb they are using along with their specs it will make for even better info.

Anyone care to measure up one of the newer carbs too?

The bike goes like the hell only from low to mid I have little power hole.

what difference is there between cck and ddk, i'd like to try them but can't find them in italy.
thanks

the DDK has a different lenght(leaner) and taper(richer) to the CCK
but the power charateristics with PWK 38 isn't smooth enough for me I will try a KTM PWK 36-S AG carburator

If your looking for smooth you might be better off with the 38.The 36 will have much more direct low to mid throttle response, arm yanking if desired and of course properly jetted. Not a big deal for the guys who ride orange because of the ease of changing to different power valve springs to tame the hit. I did a 36 and air foil back in 02 and took it out , just to much yank for gnarly northwest conditions.

This is what I found on my 09 EC250R for Hawaii

38p/172m/2 1/4as - good traction, slow rev, excellent mpg

40p/172m/2 1/4as - good traction, great power, revs good. Current jetting

42p/180m/2 1/4-1/2 - motocross like, lots of power, quick rev signs off early, low traction wheel spin

We ride between 300-2000 ft. 1st - 3rd mostly. Gearing 12/51

I just ordered and put in a CCK needle in my 11 300, at first the bike ran like crap, couldn't get it to idle, terrible response ....blah.....blah.... swung back by the truck and put the N1EF back in and same thing. So I got to rooting around with a few things and found that my choke had hung up slighty when I tilited the carb to change the needle. Fixed that, threw the CCK back in and Oulaaa. Bike now has a very linear pull. Definitely pulls harder than the N1EF, (had my buddies identical bike with stock jetting to compare to). Went with the Air Screw 1 1/2 turns out, and had to touch up the idle a hair. Also dropped to a 38 PJ from 40. All I can say is the cable choke is garbage. Take it out everyone, there literaly is only two turns of crappy plastic threads holding that POS in! I've already order a Yamaha choke assembly off a PWK carb. $30 or something like that but to me its worth it. Hard to argue with simplicity for a part like this. Its not like its hard to get at.

I've also ordered a N3EH KTM needle to try out but so far, I'm liking the CCK

That was the first thing I change on my GG.
This cable shoke is rubbish.

But with the CCK my GG runs terrible.
Which jets you use and in which envoirement you ride?
