Here's a suggestion: Someone with a current model Touring bike or Convertible scan and post the instructions from your manual detailing how to enable or disable the system. Cuts out all the who shot John misinformation.
For those who don't have rider controlled EITMS, it can still be either turned off or turned on by the dealership or through the use of software packages like TTS MasterTune.

Oh, and btw, ezpgh is correct, Harley changed the system so that now you don't have to have the engine shut off to do the enable or disable routine, you just have to be at idle sitting still. However, that just enables or disables the ability of the system to work automatically, it doesn't mean you can shut down the rear cylinder at will by rolling back the throttle. The other conditions must still be present for the system to shut down the rear cylinder, ie. cylinder head temp, rpm, sitting still, throttle position, etc.
Enable/Disable EITMS
1. Turn the ignition ON with the bike at idle and not moving (the bike may be running or not running).
2. Push the throttle to roll-off position and hold.
3. After approximately 3 seconds, the cruise indicator will flash either red (disabled) or green (enabled).
4. Repeat procedure to change.
