Help - 2007 EC 200 jetting
I have read evrything regarding jetting on this forum , the problem is I live in South Africa and have limited access to the different needles described in this forum . The local Gas Gas agents recomend and use a needle that canbe purchased from KTM agents - N3EH , however I dont think this needle works well in the 200 , but I might be wrong that is why I am posting to get advice !!
I have also tried a N3CG needle which is a little better but still not perfect , I know that it is richer on the straight portion and half a clip richer on the taper . I think these needles are too lean on the 1/4 to 3/4 throttle range , also when I do a plug check it is black and wet ( this confuses me even further . Altitude : 1600 m above sea level ( 4000- 5000 ft) temp : 40 -60 deg fahrenheit ( winter ) 70-90 deg fahrenheit ( summer ) currently in winter The humidity is low and quite dry especially in winter I use 95 pump gas unleaded and premix ratio of 40:1 full synthetic oil ( GRO) My setting with the N3EH needle was as follows : N3EH # 4 ( at #3 and #2 there is a bog or slight hesitation when giving throttle from low RPM's in the midrange , WOT there is no problem ) Main jet 170 Pilot jet 42 ( cant quite get the airscrew correct and idling was not great - settled on 2-21/2 turns out # 6 slide float level is correct plug was black and wet with these settings , My feeling was that mid was lean and top rich N3CG 34 ( also hesitation in the mid when cranking the throttle from low rpm's with #3 and # 2 clip positions ) main jet 168 Pilot jet 40 , airscrew 13/4 out , idles better now but not perfect This setting is better but I still believe it is not the best , Please advise me ,I am limited with needles here , I can get the JD jet kit but will take a couple of weeks , would this work? |
Why not order some of the needles others are having success with from the USA or Europe?
|
Who do I buy the needles from , I have dropped a mail to Les at LTR a couple of weeks ago but I have had no reply .
Where can I purchase the CCL , CCK , DDK etc needles from? |
Those needles can be purchased from Sudco International
http://www.sudco.com/ What size is your carb? Seems some guys are having better luck with the 36mm carb. Also it never hurts to e-mail JD Jetting or RB Designs for help/suggestions. JD Jetting has great prices on slides and complete replacement 38mm PWK Airstriker carbs. Not sure he has the 36mm available but it never hurts to ask. |
Thanks , will email JD jetting have used his kits in all my 4-strokes

I have tried emailing James Dean , but I keep getting a " returned to sender "
Has his email changed , I got it directly from his web page |
So last night I went through all my spares from previous bikes and , hey , what do I find , two LTR needles that I purchased from Les in 2004 .
I have the LTR -0 and the LTR -1 , now all I need is some advise on what settings to run for a 2007 200 . Please all as much advice as possible would be appreciated . altitude 3000-4000ft temp 60-80 F slide #6 PWK 38mm fuel 95 pump gas oil ratio 40:1 GRO synthetic humidity low Thanks in advance |
Go right to the source and e-mail Les at LTR Racing. I'm sure he can advise you on those 2 needles and if they will work in the 200.

I have emailed him already a couple of weeks back to actually purchase needles , but he still has not replied , I got his email from his web page .
