On the 09 bikes, the Engine Idle Temperature Management System (EITMS) is now rider controlled by twisting the throttle forward. Does it mean that the automatic option does not work any more? (The automatic one means; when the engine reaches 287 F degrees it turns off automatically the rear cylinder fuel injector).
Thanks in advance.

Rider sets the auto feature

Hi,
The feature is defeatable by the throttle. Rolling it forward can cycle the feature on and off. When it is off the cut out simply never takes place. With it on, the cut off occurs at a preset temperature threshold. It does not simply cut off the cylinder anytime you stop. Only at the preset.

Cheers,
Ed

For 2009, all FL (touring) models will now allow this feature to be rider activated. In simple terms, when at a stop with the engine idling, the rider can roll the twistgrip forward for a duration of 5 seconds at which time the cruise control activation light will indicate that RARCC (Rider-Activated Rear Cylinder Cut-Out) has been de-activated or activated.
No more automatic mode.

Hawkmann, I have few more questions

For 2009, all FL (touring) models will now allow this feature to be rider activated. In simple terms, when at a stop with the engine idling, the rider can roll the twistgrip forward for a duration of 5 seconds at which time the cruise control activation light will indicate that RARCC (Rider-Activated Rear Cylinder Cut-Out) has been de-activated or activated.
No more automatic mode.
Does it mean that in any stop, no matter what the engine temperature is , I can a activate the EITMS and it will turn off the rear cylinder?
In order to cancel the RARCC , let's say when start moving again, do I need to roll the twist grip again forward to deactivate it or it will be deactivated automatically by rolling the grip in the clockwise direction?
Thanks.

During hot idle, or when the motorcycle is off-throttle and running at hot temperatures, EITMS shuts off fuel to the engine’s rear cylinder, leaving it to idle on the front cylinder only. Without combustion, the rear cylinder and exhaust header will begin to cool, bringing relief to the rider (and passenger) soon after. Once the rear cylinder cools to a predetermined temperature, or as soon as the rider accelerates, both cylinders resume operation. And by maintaining constant rpm during rear cylinder “shutdown,” transitions between one and two cylinder operation are nearly seamless.
EITMS is purely for rider comfort. When it activates and “shuts off” the rear cylinder, it’s not because the motor is overheating. It’s designed to reduce the heat radiating from the rear cylinder to the rider.
