if you look at the spec sheet on s&s website, they recommend a range of .028 to .0295 intermediate and .062 to .068 on the main jet for a stock engine of your size. The .031 you mentioned may be a little rich, especially since you always have warm weather. I've got a 90" stroked shovelhead, which I sometimes ride when it's 30 degrees out, and i'm only running a .0295 intermediate jet. If I were you, i would avoid going too rich, especially in the intermediate jet, as it will destroy your fuel economy.
