FC22 - stick with the single taper needles. If you are lean on top go to the 14 67 after exhausting all cip positions on the 1468.
Here what I would do first, because it is easiest: Bump the main one - 185. You can do this just by turning the carb on its side, and accessing through the float bowl drain bolt. If that is not the answer, raise the needle one (4th clip). If you bike is now smooth, no spooge, and slightly lean on top, you are almost there.
If you must monkey around with the stock KTM needles, drop the pilot and main. This will help your gas milage, and still shouldn't be too lean.
Good LucK!
