What a day.
Today the Road King got a Stage One Screamin' Eagle upgrade at Sun Harley-Davidson in Thornton Colorado. This consists of a "Ventilator" high flow air intake assembly, slash-cut Street Performance mufflers, SE platinum spark plugs, and some sweet red SE spark plug wires. Then a technician put the bike up on the dynamometer, hooked it up to a computer equipped with an H-D SuperTuner, and remapped the ECM for maximum performance.

The job took several hours, and the service guys at Sun did a great job- hats off to Gennaro and his team. They even let me observe the dynamometer run, which was friggin'
awesome. When they put your motorcycle in the dock and run it wide open, it is
deafening- Rocky Mountain thunder, baby!
After making my way thru afternoon traffic, I finally got out on CO 128 and explored the bike's new capabilities. I was doing 60, and
still in 5th gear... the pipes were just purring behind me. I could crack the throttle open and accelerate up hills that used to have me downshifting. The difference in performance is remarkable.
Instant throttle response.
Big-time acceleration. This bike will eat Vail Pass for lunch. I'm going to have to re-learn how to ride it, given the increased power and performance.
And the new pipes sound beautiful. Not louder... but a deeper, fuller exhaust note. But when I crank it, oh man... they
roar.
Here's some video of the bike on the dyno that I shot with a Canon PowerShot A490:
