Any reason not to enable the rear cylinder cutoff?

Yup, I'd say that would do it, especially if you were already fully warmed up before you got stuck in that mess.
According to my owners manual (09 Ultra Classic), it says to turn the ignition switch to the "on" position, the run/kill switch to the "run" position and "do not" start the engine," so that pretty much answers your question.
Roll the throttle to the full off position and hold it for approximately 3 seconds. Afterwords the cruise control light will either blink green (enabled) or red (disabled). You can release the throttle and roll it full off again to toggle the EITMS between enabled and disabled.
FWIW!

My understanding is you can't "turn it on" in terms of "making" the engine go to one cylinder. You CAN "Enabe the system or disable the system" but the engine temp has to be "X" (and I dont know what that magic temp is or if Harley even reveals that number) before it will turn on and it will only turn on if it is in the enabled position.

Maybe someone else can clarify that one for you!

As others have stated mine was disabled but the salesman enabled it before I left with it. Im curious although I woulnt think so, but is fuel still being delivered to the rear cylinder when it stops firing? Is it possible that you could eventually wash that cylinder out with fuel or saturate the spark plug with fuel?

No, the cylinder it shut down by stopping the fuel flow. If all it did was cut the ignition but kept supplying fuel, you'd be filling up the exhaust with raw fuel that would either be ignited by the exhaust of the other still running cylinder or would make a nice "bang" when the disabled cylinder fired up again. I would assume that the ignition keeps firing normally but could be wrong about that.

Rear Cyl cut off
I know you can "enable" the system....but my understanding is that by "enabling the system" is not going to automatically turn off the rear cyl unless it has already reached that magic temp that Harley set up to trigger the system. Thats what I meant. I'll try it for myself in non-overheat temp conditions and see if the rear cyl cuts out.
