Here is what I am running in my 04 DE300 at 900 ft. elevation.
42p N3EH 3rd clip 178m I would say its performance pretty much mirrors what Dave says about the N3EG. My tail pipe isn't perfectly clean but the bike pulls as strong and clean as anything I have tried so far. I would try a 175m but I don't want it to pull any harder on top! I'm thinking about trying that 1369D to help find the finish line next year when I ride long course. |

Now I've tested the following jetting. 42 N3CG#4 178. And I'm very happy about the results. Now I can give full throttle on a high gear from low RPM's the motor gives plenty power through the hole RPM scale without any hesitation. My bike has never felt this good. Thanks again Dave |

Pobit,
I ran your jetting suggestion; CCK needle on middle for the first time yesterday and it was sweet. To be precise I ran 42 pilot, CCK on middle, 180 main and #7 slide. Pull was very smooth and linear which is what I wanted. Still not sure if I want to keep the bike as while it is now much better it's still too strong for me. It's great fun for a while but a lot of my events are tight, wet woods and run for 5 - 7 hours. A 250 thumper would probably yield a better result being nice and mellow. |

Hey Steve,
The needle I'm using is from Les Tinius at LT racing. I am using his jet kit. It must be noted that now I am using a #8 slide also.

You are mirroring the jetting I used on my '05 EC300. Now, if you get your head worked over, your going to pick up a ton of low-end. I tammed mine back to reasonable output with the CCK needle, going back to the #7 slide and dropping a tooth on the rear sprocket. If I go out to the desert, I'm swapping to the #8 slide and possibly the LTR needle. Its a beast jetted that way with Ron's headwork, but I like it when things are more open.

Rode the bike with Pobit's jetting in an event yesterday and it was the best it's ever been but I still want a 250 thumper. There was one bit of the course where I was glad of the power (2 foot deep mud) but most of it cut up badly in the trees, was slippery and tight and a 300 2 stroke just isn't the tool. I might keep it though for when I do more open fast courses. Yesterday's event was over 90% in trees so close you often had to stop and squeeze the bars through. I'd like to try a GG 200 in an event but that's difficult to arrange. I like 2 stroke simplicity but I really struggled with the 300 towards the end of the competition - just couldn't open the throttle slow enough for my tired arms and shoulders even with a G2.

Thats why the EC250 is so good. Most of our events on the east coast USA are like that, especially southern NJ.
Try backing off your timing 1mm and adding a base gasket to drop compression a little. Does the bike have the OEM reed spacer or was it removed? |

New EC250 2008 jetting
I have just bought a new 2008 ec250. Its a fantastic bike! I have owned 3 250 exc KTMs and a YZ 250 but the suspension and handling of these GG's is just incredible.
My only complaint is the recommended factory jetting is off, being a little rich of the bottom to mid but has a strong linear pull from mid to top. My current settings are: PJ 40 Needle NIEF #3 MJ 180 Temp 50 to 70 F I lowered the needle to #2 and she runs a bit crisper but still not ideal. The local agent recommends the following settings which he says works on many bikes here in Greece: PJ 42 N1EG #3 MJ 178 I feel these settings will be really too lean. I called the Keihen agent for a CCK needle but the don't have it in stock and will not import them. Should I go to the equivalent Honda needle if available. Any suggestions? |
