Jetting Database - PLEASE ADD YOUR SETTINGS

[iancp5]

I checked some threads over on KTM Talk for their 200 and no mention of using the CCK needle. The 300 yes.

Here are the popular choices that seemed to come up the most (and JD needles of course).

CEK, CEL
DCJ, DCK
DDJ, DDK

Not sure if that helps or not but something to think about.

Too much to think about! I'll have a look at the KTM site and see what they're saying.

My 300 came with an N1EF and the CCK was smoother so I was wondering if it works well in the 200. The other complicating factor is that currently it's fitted with a 36mm instead of the 38. When moving down in carb size what jetting changes should I expect to need? Currently it runs ok but not spot on. There is a power hole in the midrange. Not sure if rich or lean, I suspect rich. I guess dropping the needle a notch will soon tell me. It pulls then goes flat in the high midrange and then picks up again on full revs.

Yes have a look at their site to REALLY get your head spinning. I find it very interesting to compare the GG and KTM's in jetting as they seem to be quite similar with the same sort of issues.

The KTM 200's came with 36mm carbs for awhile also and most seem to be using a #6 or #6.5 (KTM weird thing I think) slide.

The guy Jersey Devil over there really knows the 200's so look at allot of his posts. There are others as well but he comes to mind. There is sooooooo much info your head will hurt after awhile.

I'll have to try the CCK in my 07 300 and also the N3EG? that Pobit recommended.

I thought it worked really well. Smooth but with no noticeable power loss.

Bike year & model = 2002 EC250
Temperature (degF) = 10 to 30 deg C
Elevation (feet) = 1900-2600FT
Main jet = 178
Pilot jet = 42
Needle & notch = LTR #3
Air screw setting = 1.5
Throttle valve/slide = 7

Result: Mid is a bit rich but bike runs way too hot with the needle in #2 position. Bottom end is great.

-------------------------------------------------------------------------
Bike year & model = 2005 EC250
Temperature (degF) = 68-104F (20-40C)
Elevation (feet) =2600 (800m)
Main jet = 180
Pilot jet =40
Needle & notch = NIEG 2º from top
Air screw setting = 1 turn from closed

Results:
The Brazilian gasoline has 25% of alcohol. So this is the best we can.

Ec200 2004

Bike year & model = 2004 EC200
Temperature 0-20C
Elevation (feet) = 0 - 500
Main jet = 178
Pilot jet =42
Needle & notch = N1EE #2
Slide = #6

Bit flat in the middle but could be the dent in my pipe.

 

[whodat]

-------------------------------------------------------------------------
Bike year & model = 2005 de 200
Temperature (degF) =62-95
Elevation (feet) =1500-5000
Main jet = 172
Pilot jet =42
Needle & notch =LTR, middle notch
Air screw setting =2 out
Throttle valve/slide =# 7 with power-now(this cleaned up jetting from top to bottom)

Results:wide open jetting is easy, the transition from the basement to the mid was difficult. Technical terrian requires(from me, anyway) great jetting from idle to 1/4 throttle and the power now mod combined w/pilot and air screw being just right was critical. Poor idle was handled by cutting a little off a the spring on the idle adj screw. I know it is "primitive pete" but it works.

Bike year & model = 2004 EC200
Temperature (degC) = 5 - 20
Elevation (feet) = 0 - 500
Main jet = 180
Pilot jet =45
Needle & notch = CCL #4
Air screw setting = 1.5 out
Throttle valve/slide = #6

Pobit recommendation and spot on. Smooth power and torque no holes no surprises. Very pleased much better than previous jetting which was the more common 200 setup in the UK.

Bike year & model = 2002 EC 300
Temperature (degF) =12c-38c
Elevation (feet) =0-1000
Main jet = 180
Pilot jet =40
Needle & notch = N1EF 3rd clip
Air screw setting = 1.5
Throttle valve/slide = #6
Was running a 38 pilot but had moments of it running 'surgy' when hot,idle would waver a bit.
Now pulls hard & consistent off the bottom,smooth strong mid & a 'holy shit batman' top end.

Bike year & model = 07 EC 300
Temperature (deg) = 15-30
Elevation (feet) = 0-1000
Main jet = 180
Pilot jet = 42
Needle & notch = n1eg 2nd from top
Air screw setting = 1-2 turns out
Throttle valve/slide = #7

Results : Very smooth right through the rev range no bogging or flat spots.
Heaps of low to mid and mid to high range power( right through I guess).
Stock except for fmf powercore2 muffler.

What's the difference between the CCK and the CCL?

Just bought the CCK for my 250, not tried it yet.

I just put in the CCK and like it. The CCL is slightly more lean than the CCK. The last letter L vs. K is the needle diameter. The CCK will be slightly richer off idle up to 1/4 throttle... assuming all other jetting, temperature, etc. is the same.

 

[GG27]

Hi Matt, what is your jetting specs since I;ve got a CCK to try out and compare it with my LTR.

Thanks

Please see the summary list here:

My latest jetting is dated 3/22/2009 under the 2007 bikes and works very well for me.

EDIT: I posted the link above to remind folks that I make a complete summary list out of all entries here. I hope the summary list (pdf file) is convenient for folks to review all database entries.

Yes thats one of the best things on this site. You did a great job.

LTR Needle comparison

Does anyone know what standard needle the LTR needle is similar to?
I am trying to compare this needle with other standard needles in the JD jetting program referenced elsewhere in this forum. I have just done a head squish mod (now 1.25mm & 170PSI) & raised the base gasket thickness by 1.2 mm to align the top of piston with bottom of transfer ports and the bike feels flat mid to top-end. Currently running 45PJ, LTR #3, 182MJ, #7 slide & 98 RON fuel @ 50:1.

CCk is very similar I do belive. Quite a smooth needle.

 

[GG27]

The LTR starts out as a DDK needle. I would go to a 180 main, 182 ran too fat in my 250. I also tried a 45 pilot with a #8 slide when the weather is hot and dry and the bike rips. I would also try CCK #2 with 180 MJ and 42 PJ as suggested by Matt.

 

[GMP]

There were three LTR needles total. The first two were close to C series taper, the last a little richer like a D series.
