I totally forgot what I'm jetted at. Mines a stock carb.
Best bet is to call up and ask a mechanic at  Sun Harley, Freedom Harley, Mile High Harley, High Country Harley, or ask for Randal at Deluxe Motor company.   
  I'm sure someone would have a good answer for ya. Good luck and welcome to Denver!
