I tried out a CCK 2nd click with 42 pilot and 178 main on my EC250 today on the MX track with about 10 C outside, bike seemed really lean, making a raspy sound in the midrange and cylinder was really hot on the back side, so I switched to the standard N1EF on the second click with the same pilot and main and bike ran much better with more power. CCK gave a little more torque in the low to mid revs but signed of sooner. Can you tell me why all the fuss for the CCK?
