507 Posted November 5, 2015 Should i rejet all 3 circuits or just pilot? Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 8, 2015 What are your currently running, what temp did you set it up for last, what is your altitude and planned temp range? The airscrew will tell you if you need to swap the pilot, I would buy a 38 preemptively. You will have to swap to a bigger main. You shouldn't have to touch the needle if you have already found a good setting before now and you pick the correct pilot and main. Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 8, 2015 I've been testing the stock 2008 RM 250 needle (NEDJ) and I will say if you plan on opening the top of the carb give the NEDJ or NECJ a try. It's everything people say it is. Share this post Link to post Share on other sites
peaceofwork Posted November 9, 2015 I have a 2015 300TE that I am about to mess with I have no idea whats in it now for jetting. I have picked up a NECH needle for it along with a ktm SXS head. I have played with a few 300 ktm motors jetting so I shouldn't be to far off I am in the pacfic north west and I plan to start with pilot 40 mainjet 168 needle nech middle clip position sxs hi compression head all else is as it come from the shop.

peaceofwork Posted November 9, 2015 anyone have any pacfic north west jeting recommendations 0/4000 ft trail rider here Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 9, 2015 How did you settle on the 40 pilot? I'm new to owning a KTM and on the East coast, but unless it is already cold as heck where you are, that may be too rich. Share this post Link to post Share on other sites
507 Posted November 9, 2015 So sorry i asked this with no data. 40degrees and 700' stock jetting, gotta look. Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 9, 2015 At 40F and 240ft I think I would still be on a 38 pilot in my 05 300EXC, but I just got it earlier this month and have only put about 8hrs on it. I'm using the 35 now. Share this post Link to post Share on other sites
507 Posted November 10, 2015 I guess i hear about tge suzuki needle but would this work for cold weather too? Dont want to lean it out of season. OR do people use this necj needle and just re pilot when air screw is n more than 1-1.5 and then put 38-40 main? Share this post Link to post Share on other sites
507 Posted November 10, 2015 Sorry meant pilot 40 and bump main up one Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 10, 2015 The needle can affect the main jet circuit. However, my switch to the suzuki needle did not require me to change main jets. Since what the needle does is control the transition from pilot to main and vice versa by altering the flow of the main jet, it is my opinion that one needle can be used for all seasons if it works well. I typically don't even change the clip position once set up, because with the correct pilot and main changes for weather there is no need to as long as you are not changing pipes and such.

clappedoutkx My Rides (4) Posted November 10, 2015 (edited) Yeah if the airscrew is turned in richer than 1 turn out, it is time to go up one on the pilot jet, and probably the main as well. Always confirm the main; its easy as cake. Edited November 10, 2015 by clappedoutkx Share this post Link to post Share on other sites

507 Posted November 10, 2015 What does "confirm main" mean? At speed? Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 13, 2015 Yes, confirming main jet sizing is conducting a plug chop, dyno pulls, or using your butt dyno, if it is calibrated. Don't fall into the trap of riding around for a day and then looking at the tip of the plug. That's not how a plug is read and will only provide confusion. Read "Spankys Jetting Guide" or "Is Your Two Stroke Running Rich?", and let us know if you have questions. Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 13, 2015 The needle I went with is NEDJ. It was used on the 2008 RM250. I have not tried the NECJ yet, but I believe it is basically the same, but half a clip position leaner. I suspect either needle will do the trick for you. 1 Share this post Link to post Share on other sites
peaceofwork Posted November 14, 2015 what exactly is the difference from NECJ/ NEDJ? Is it whare the taper begins or? perhaps the angle of the taper on the needle? Share this post Link to post Share on other sites
clappedoutkx My Rides (4) Posted November 15, 2015 The clip positions are machined 1/2 position leaner on the necj. If you have the nedj and can't decide if you want the clip in the 3rd or 4th position, and want a 3.5, the necj is for you. So, either needle should work fairly well, but I've only used one of them personally. Share this post Link to post Share on other sites
