Ok, I wasn't able to get home during lunch so I just tried to run the procedure described to me above.
I got the following codes, all under P:
0113
0134
0154
0031
Then part number Pn-32933-11
HELP!?!?
Oh yah, I called Jamie and he (very politely) told me to call back with the codes.
HELP!

Just came across this thread surfin' for info as I'm getting a "new" 2007 RK soon and trying to get up to speed on it. Looks like from his codes he was missing something with the O2 sensors when he reassembled after the Stage 1 kit; maybe the resistor plugs? I'm sure Jamie figured it out real quick for him.
P0131 Front Oxygen Sensor Low
71. P0151 Rear Oxygen Sensor Low
72. P0132 Front Oxygen Sensor High
73. P0152 Rear Oxygen Sensor High
74. P0134 Front Oxygen Sensor Inactive
75. P0154 Rear Oxygen Sensor Inactive
76. P1510 EFI Limited Performance Mode
77. P1511 EFI Power Management Mode

And having no load at the O2 sensors would make perfect sense.
They are a critical component to the machine functioning, and if they are "open" the ECU will certainly catch this, and set a code.
The ECM uses these to monitor hydrocarbons being emitted (probably thermally based on algorithyms-mathemaical tables stored in the ECM) and makes adjustments to the AF to keep it running at the proper emmisions. If there is not a component out there like an O2 sensor, or resistor, it will run on a default value and set a code.
Any machine that is processor controlled would show the same symptom if a critical system component were to fail, which is more common than one coming up missing.

Right, I thought the O2 sensors on any engine were critical to the ECM calibrating the fuel injectors for air/fuel ratio? Hard to believe you could "improve" the performance of an engine by eliminating them all together? Still learning about this new ( to me) HD fuel injected computer controlled stuff. I don't think my truck would run if the main O2 sensor went out?
Btw what does "tag this one" mean?

Cool, Jswerve, really looking forward to learning more about disconnecting O2 sensors on the Harleys.

My check engine light came on after I installed cams, just had to do a slight adjustment on my mapping....no problem. Infact it still comes on once in awhile for a couple secs. when I give 're

Just a follow up tony original post. It seems my PCV wasn't working properly. After working with Fuel Moto over the phone for a while, they decided to send me a new PCV.
Once it arrived, 10 minutes later everything was perfect.
