Revised Jetting Specs NEDW

[Jakobi]

No risk in changing jets around, as long as you know your last working settings. Know that feeling you speak of looking for another gear

Heading out this weekend for some more tinkering. Bikes been prepped with the 40P AS 2 out. N3CW#2. 170 Main. Hope its on the money.

Going to drop the pilot 1 size as i had to come out to 2.5 turns and could have gone a bit more to clean up the bottom end. Mid range is crisp but signs off up top a bit. Going back to the 172 main. Slight hanging idle if thrashing around on the main for too long.

Update: Dropping the pilot didn't help clean up the burble on the bottom end. Just resulted in hard starting and caused hanging idle to get worse. Even with the 172 main. After a few sessions up and down the street the only way to clean up the low - mid range was to lift the clip again. Ended up with nice crisp response right off idle. Less vibration in general and a bike thats happy to sing sing sing on the pipe. Smooth and controllable off, and will idle on the stand for as long as I want. 40P AS1.75 NEDW#1 172. I still have no idea why my bike in particular requires such a lean needle to run crisp. Will be doing 180kms of wet sloppy forrest, red clay fire trails, and some nice rocky mountain climbs tomorrow. Should be a good test.

with the weather getting cooler here, my NOZH 42 pilot combo idles very well on clip 1. I got the air screw to sit at the preferred 1.5 turns out pretty much all the time.

I am still at a 160 main. I went to a 165 and the bike had a hard time revving out. 160 just rips your arms out.

I did try the N3EH I had and it idles about the same, but I use much more fuel with it. It runs a little smoother than the NOZH. 170 main if I use the N3 needle.


What I do notice with any needle is that if you putt-putt around off the pipe for a while, the bike won't idle right with any needle in it. If you ride it a little harder, and are just coming off of being "on the pipe" the bike idles perfectly. Not a hanging idle, but just right. If I stop and it is idling low, I just bump the throttle a little and it idles higher.

had a few minutes.. put it in.. feels great so far..
real good crisp low end.. will carry front wheel easily thru 3 gears..
nedw.. ctr clip for now.. 40 p 170 m as 1.5

Glad to hear its running well. Would love to see/hear some video. Any burble at part throttle?

Just to summarize could you put down previous jetting specs, along with elevation, temp, humidity etc. Just helps for others to have an area for comparison.

it burbled once about 1/3 throttle, but i think it was not fully warmed up..
once warm it ran great..
i am in amarillo TX 79109.. we are 3500', but our air here is horrible.. we sometimes have a corrected altitude over 5000.. it was about 80 today and maybe 20% humidity.. we are in a huge drought.. previous jetting is not much help as this bike came from the houston area, but it was 182 main, 42 pilot, cek clip 2..normally, on my other gg.. 40 to 42 pilot, both bikes have 170 mains..
will give it a good ride hopefully next weekend.. hopeful get some video time.. thanks jakobi..

Tried moving the clip from #2 to #3 and rode about 30 miles. Result was too much blubering. Switched back to #2 position and 50 miles of very nice jetting.

'05 DE300, 38mm PWK, #7 slide 170M/38P/NEDW#2,2 1/2 out.

4000' elevation, 60 degrees.

Other than handing over the carb to RB, this is pretty darn good setup

I'm going to give this a try next time out just for giggles cause I can't help myself I was pretty happy with the 40 NEDW#2 172, bit burbly in the lower openings. At clip 1 its very nice off the bottom end and lugs like a tractor but feels a bit weak/flat right before it comes onto the pipe, then it rips.

Dropping the main 1 and the pilot 1 might clean up the top and bottom while still giving it a beefy mid range. Tinker tinker tinker.

Good to see others are having good results with the needle. Good call MJC
