When using the JD kit, most people are using pretty close to the same settings. Either stock (45) or 48 pilot, 168 main, JD red or blue needle (depending on your conditions). For So Cal, the red needle is recommended with the clip moved down (richer) one position from the center position, which is the 4th groove. I think I also went with a 50 leak jet, which seemed to help the off idle hesitation I was getting. Bike runs very strong with this set up, but of course the pea shooter has to go as well. I ultimately went to an FMF slip on which helped the bike breathe even better along with a Uni filter.
