2010 EC300 Factory Jetting Specs - WTF?

[Jakobi]

I've run a JD kit on my previous wr250F, wasn't sure how they'd go on the gasser so thought i'd try a few cheaper needles first

[Jakobi]

Has anyone made any changes or tried any other settings recently?

Jeffs, how did the bike run with the 178? Did you ever move up to position 2?

I tried the needle in second clip and the bike ran horrible. It would act like it did not want to rev at all on the bottom, kind of like when the bike is not warmed up. I then moved to the 4th clip and that was much better but still not as good as the 3rd clip.

For yesterdays ride I installed the 178 main, 40 pilot, 3rd clip a.s. apprx. 1.5.
I think this is about as good as it gets with the N3CH needle. I may try running a 42 pilot and cranking the air screw out a little farther to see what that will do.

I am pretty happy with it overall. It runs very smooth throughout the rev range. If I have any complaint I would like a little more snap down low but honestly I am probably faster with the smoother power delivery.

.

What altitude and temp was this ? Might be that in the 2nd clip is just too lean ?

[jeffs2200]

About 500 asl about 55 f. I am sure you are correct about it being too lean. I just wanted to try and see if it had more snap but it did not work out to well.

Last week, we had a nice 65 degree, 61% humidity day so I took the 300 out for a few minutes for a quick plug check. 38 pilot, 175 main, N3EH needle in the 3rd clip and A.S. at 1&1/2 turns out. Plug was a perfect light chocolate brown.
