I have tried a few different combo's and still not real happy with the results. I am back to 55 pilot, CEK mid clip, 168 main. When I had 155 main in it felt like it was falling off up top which I thought I was running out of fuel, but this sounds to be rich doesn't it? Still have not played with idle too much, very hard to start now. I am going to dyno it in a couple of weeks at a local shop who stocks plenty of jets, but they do not stock needles. I have a CEK, DEK, and CGL needles, I would like to take two or three others to try. Could you recommend any others to try? Also switched to Trinity pipes, good mid range, poor low and top. Thanks for all the input.
