This is about all you can get without modifying the heads and changing the cams. If you go for high dyno numbers you will lose some of your low RPM torque and it will make your heavy road king less streetable. Also the crankshaft will have a much shorter life expectancy. When the crankshaft run-out becomes excessive it will then destroy the oil pump. My advice would be to get the fuel mixture just right so the engine will produce the best power at the speeds you normally ride.07 road king with up grades and dyno at 68 hp why?
Probably jetting, or the fuel mixture if it's injected. My '03 is still stock 88", with stock cams, a Screamin' Eagle race module and coil, Bassani Pro-Street pipes, and a Daughrty Powr-Pak air induction system, and it dynos at 81 HP. I'd suggest having it dyno tuned, if you haven't already. Most H.D. dealers have the facilities to set you up.07 road king with up grades and dyno at 68 hp why?
Ancient low tech push rod engine design limits HP. By comparison 100 CI Victory with Stage 1 kit is well over 90 HP. Still a V twin but 4 valve OHC oil cooled. If you are interested in HP you own the wrong brand of MC. There is a video on YOUTUBE of a 110 CI Screaming Eagle Harley getting smoked by a stock 100 CI Victory Jackpot.
You should be approx. 80 hp, trash the Power Commander and have your dealer re-flash the ECM with the Stage 1 download.
