Default Jet kit questions

I know that when adding after market exhaust and air intake systems, the carburetor has to be re-jetted. I have heard that the use of a "jet kit" will rob you of fuel mileage. I used a vance and hines kit once and i did notice a drop in fuel mileage. If this is so, what is the best advice for jetting a 2005 tc-88 road king, with vance and hines oval slip ons and a k&n filter kit, with out using a "jet kit"?

Drill the welch plug out to access the air/idle mixture screw, and set it at 3 turns out, install a 46-48 pilot jet and a 175 main for starters.
