When I called Sudco they said Kawasaki has a proprietary needle with a triple taper therefore they don't offer replacements. I have a '91 KDX 250 with the stock Kehin, a 38 mm carb with a R1368H needle. Is this hog wash?
I've read you conversion charts Canadian Dave and my calculations tell me that my next leaner needle choice is a CEJ with only a slight length difference then a CGJ as my stock needle would be a C-X-J. (X is defined as somewhere between D and E). A CGJ would lengthen it by approximately 2.475 mm that is if the table can be interpolated. I say this because my L1 is not a standard Kehin available L1, it falls somewhere between Kehin's D & E. Next leaner would be a CGK which would be approx. 2.745 mm longer + .01 larger diameter. And finally a CGL, 2.475 mm longer +.02 larger diameter.
I'm wondering if the guy on the phone was referring to the proprietary setup regarding the lack of direct conversion from my stock needle to an available to the public Kehin needle. And the triple taper stuff was nonsense.
Kawasaki offers two leaner needles. One is +.01 larger diameter and the next is .02 larger. The kicker is they're $18.00+ a pop. Has anyone gone this route?
In case anyone wants to know I'm running a 40 pilot and a 158 to 160 main depending on the cold. I'm running slightly rich between idle and 1/8. Very rich 1/8 to 3/4. And right on WOT. I know a few of you are fond of changing out the slide but I'm on a low budget as the Kinks would say.
One more question! If I go with a leaner needle should I start out with my richer main because I really don't want it to much leaner on top and I know one circuit has an affect on the others?
Please advise! Thanks.
