I'm the third owner of a 2006 XB12X with 14k miles. It has a Buell performance muffler, high flow air filter and re-mapped stock ECM. The interactive valve actuator cable was removed.

The red check engine light comes on when I run the bike hard. The light turns off when I slow and come to a stop. I cycle tested the actuator and watched it close/open/close. If I reinstall the actuator cable, would this stop the check engine light from turning on?

The bike runs great. It has an occasional hiccup when cold at startup, but this goes away once it's warmed up. The only issue is the check engine light.

Sounds like your getting a bad O2 sensor light. Mine did that. At highway speeds the light would come on but when I slowed down it went out. I checked the codes with ECM SPY and it was the O2 sensor. I replaced it and problem solved. If you have access to ECM SPY or other software check your codes. You can also short out two connections on the computer connection and count the light flashes on the dash. There's instructions in the manual or somebody here can give you that info.

buellmods.com will give you a FREE .pdf download explaining how to check why the CEL is on.

Alternatively ECMDroid is free on google play store and in a wonderful diagnostic tool to have. It connects wirelessly to your bike with a bluetooth dongle. I like the one I got from Buelltooth.com, now Rev-Mo.com

Geoff, I'm curious. Your profile page lists your XB12X as a 2008 model. Your post here says 2006.

+1 Tootal. I had the same issue. Shorted the connector pins and, I believe I got a 13 for the code, or whatever the O2 sensor code is. It was a bad O2 sensor. Happened once before, put in a Bosch O2 sensor which only lasted about 6k miles.
This time I used a NTK NGK 21002.
Been good for around 1.5k miles so far.

Thanks to all for the input. I want to rephrase my question before I start investing in software, O2 sensor, ECM re-map and more.

A stated above, I cycle tested the exhaust valve actuator and watched it close/open/close. I assume this means it's turned on in the ECM. If I reinstall the (missing) exhaust valve actuator cable, is there a chance this might stop the check engine light from turning on? Is the ECM is looking for a change that's not happening?

No, the ECM is paying attention to the actuator's feedback. If it jams or is disconnected the circuit is wrong and results in a CEL.

Making the CEL flash a fault code can be done for free by following the above noted directions.

Correct ^^^^ The ECM can't tell if the IEV cable is adjusted or even connected at all, It only knows if the actuator is working.

The exhaust actuator may cycle, with no load (disconnected), but could have problems when reconnected (because of added resistance). This valve was updated sometime after 2007, because of reliability problems.
I agree that you need to check for stored codes (even if the CEL is turning off).
If you don't have a service manual, you might try searching in the archives for detailed steps.

you need to use either ECMSPY or ECM droid and set AMC to not register - error code is perhaps 25
once you remove the tick in the box CEL light will not reappear
