This is crazy. We just installed S&S cam drive gears into our 2003 King with mid range cams. The bike was already set up with Screamin' Eagle heads, two-into-one exhaust, a Screamin' Eagle air box and Terry performance oxygen fuel sensor addition to the stock EFI system. Bike ran fine, but I wasn't capable of additional tuning options. Plus I never dyno tested it after I logged some Terry adjustment miles.

I've been told several times that Zippers is the only company making a complete EFI replacement module that plugs directly into the stock harness. In addition it makes the earlier models a complete closed loop system, with 02 sensors, for enhance performance, tuning and diagnosis. The temptation hovered over my head every time I discussed tuning with knowledgeable performance minded nuts like Gene at Gene's Speed Shop, in Carson, or Bennett's Performance, in Long Beach.

Then the iron struck like a bolt of lightening in a southern night sky during tornado season. Or was it Bulliet Whiskey, a voluptuous blonde and the phone interrupting in the middle of the night. Dave Rash called from D&D exhaust, and his bit Texas accent spilled into my whiskey glass.

"We're making an exhaust system for new EFI Harleys," Dave barked, "coupled with Zippers and an air cleaner for amazing performance. We're calling it the Bandit system." That was damn good news. D&D tunes every exhaust system they make on a dyno. I asked if it came in black. "You bet," Dave said, " we coat the header pipes externally with a ceramic coating (2000 degrees) and the heat shields and mufflers are finished with high temp (900 degrees) powder coating process."

Fortunately the D&D/Zippers system wouldn't arrive for a couple of weeks, so the blonde could stay. I delivered the blacked-out two-into-one D&D system, the Zipper's ThunderMax EFI system with O2 sensors and the air cleaner kit to Gene's Speed Shop, then rode the King down on Saturday for the installation. The first thing we did was to run it up on his Dyno and take it for a ride. It hit 80.2 pounds of torgue at 3200 rpms and held on until 3500, then dropped to 60 pounds at 5300 when it cross the line with the horsepower curve. The horsepower increased from that point to 68.7 horses at 6000 rpms. The results were just okay.

We let her cool, disconnected the ECM power fuse and went to work. We removed the right floorboard, and with a swivel- headed ½-inch socket removed the header nuts. Then we loosened the tranny bracket, and the 1/2 -inch bolts from the muffler bracket after the soft bags were removed. The exhaust system slipped right off the King. We didn't forget to remove the O2 sensor before we yanked the Screamin' Eagle system off and threw it on the floor. That system took me to Sturgis twice and to Laughlin for 90 mph ticket, plus a friend needed a system for his big inch Dyna and we were going to try to make it fit.
