Wow what a cool site!! Time to step up to some engine mods on my 04 EFI Road King Custom. I set er up at purchase with the stage I kit & slip on Vance Hines. Where to go from here? I want some punch. With the wife on the back 1/2 the time and equal city and highway riding i want a well rounded runner that's reliable. I'm liking the 103" & 113" Harley big bore kits. But where to start, which kit, heads, cams, clutch etc.... Any suggestions?
