Jetting advice
I read every page of the jetting thread and I'm still scratching my head.Here is what I have in the bike now.
2007 EC 250 N1eg Needle 3rd clip from top 180 main 42 pilot #8 slide Racing an enduro 800-1000 ft temps so they claim 52* but race will start in the 40* and may stay that cold all day .This is the set up I run all summer plug is perfect and bike runs perfect.Would I be safe going with a 185 main and a 48 pilot there are some 6th gear fields and would rather not melt it down but don't want to be to rich just in case it does warm up.thanks Mike |
What bike have you got Mike?

Some bike info would help good catch JD 2007 EC 250.Sorry I was making sure I had jetting correct and forgot the bike.

Mike,
The 185 main looks good, but the 48 pilot may be too rich. A 45 pilot may be a better match to your current summer jetting. If you went with the 48 pilot, then you may need to back out the air screw to help lean the 0-1/8 throttle a bit. You should be receiving a PM from me. :) |
I think your jetting is good for hot dry summers, I have used your setup in Greece with no problems, but for cold weather racing I would go to a N1EF needle on the 2nd or 3rd clip with a #7 slide. The 42 pilot is just right, I have tried the 45 with a #8 slide and it has similar results with the 42 and #8 slide.
I use 178 to 180 main with the F needle with a 2% full synthetic oil mix, and have no issues after long transfer sections @ WOT. Try it, it gives a nice strong mid-range. |
I'm stuck with this needle as i have no time to get another one.So have to come up with a setup around the N1EG needle. My thougts are to go with 185 main and 42 pilot and leave needle as it is set. I thought I had a 45 but do not so left 42 in and turned in air screw it is now out 1.5 turns.

Do you have a #7 slide? It will help in the colder weather. IMHO I would go to a 182 main.
|
No I don't have a #7 slide.You think I will be safe with a 182.Temps look to be around 45 degrees mid day high 30's to start race.

I think the 182 is O.K. together with a 1 to 50 oil ratio. The G nozzle has the same diameter as the LTR and CCK needles, which do not have any issues when driven WOT. I would play with air screw, I had it down to 1/2 out in such weather conditions with the #8 slide. You could also try raising the needle 1 clip as well. Ever bike is just that bit different so you have to try various set ups till you find which suites you.
Good Luck in your race |
Thanks I went with the 185 42 pilot and air screw is 1 turn out rode it last night and seemed okay.Sounds like the race is going to be muddy :eek: so speeds may be slow.Weather man is not sticking his neck out to far on temps 51-37 degrees so I'm guessing some where in the middle.
