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.

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.

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.

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.

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