Hmmmm... I'll have to get the MoCo right on that and make the correction to the 2010 H-D Owners Manual for Touring Models. (Page 146 - ..."the rear cylinder will become an "air pump" which will work to cool the engine.")
Right, but the cooling is for your benefit, not because there is any heat risk to the motor at those temps. If there was, you wouldn't be able to disable the system. HD runs these bikes in the AZ desert testing grounds at much hotter temps with low air flow.
"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."

I wouldn't worry about it. Sounds normal to me. If I am running from light to light mine will easily kick in at those temps. I can run 50 miles in the desert at 90+F though and sit idle for several minutes and it never kicks in.
Oh, and one note. EITMS is not for the bike. HD claims totally unnecessary for the safety of the motor. It is 100% for rider comfort. If it kicks in, it is trying to cool you down, not the motor.
Although the engine getting hot enough to activate the EITMS is NORMAL, don't misinterpret that as being desirable. Normal and desired are not always the same and this is a classic example of that.
While 287 degrees (the EITMS threshold for activation) will not cause any immediate catastrophic damage, prolonged operation at temperatures that high is detrimental to engine life. If the HD claim quoted above is true, I could care less - Regardless of that claim, I'd prefer my engine running much cooler.
I've installed a "parade" fan to my bike that is excellent at controlling the engine temperature during prolonged idling encountered in congested traffic conditions. Here's a link to a thread that documents how well the fan performs: https://www.hdforums.com/forum/touri...test-data.html
If you are really concerned about engine temps in rally type environments, or anytime you encounter congested traffic conditions, I highly recommend a fan of this nature.
You must be talking about the Engine Idle Temperature Management System. Basically, it turns off the rear cylinder and it becomes an "air pump" which helps to cool the engine.
All conditions must be met to activate EITMS:
- Engine temp more than 287 degrees
- Engine idling
- Moving under 1 MPH
- RMPs less than 1200
Once activated it'll deactivate if one of the following exist:
- Engine temp falls below 275 degrees
- Revving the engine
- Moving faster than 2 MPH
- RPMs exceed 1350
- Clutch released while its in gear
Your bike should have been delivered with EITMS disabled. To enable it:
1. Turn the ignition switch ON and push the OFF/RUN switch to the RUN position (do not start your bike).
2. Push the throttle to the roll-off position and hold.
3. After about 3 seconds, the cruise indicator lamp will either flash green (EITMS enabled) or red (EITMS disabled).
4. Repeat steps 1-3 to reverse the process as needed.
As for it running hot... yep, it's a Harley.
all of the above ....but mine can be turned on/off while eng running at idle by rolling throttle forward till cruise light turns green

I think he is talking about "cooling himself down", when he hear the "pump" goes off.
I think the heat deflectors are STD on all the touring models from 2010 - present.
Nope. Had to buy a set for my wife's 2010 Street Glide. I also noticed the 2011 CVO Street Glide doesn't come with them either. Absurd a $35K bike doesn't come with those things preinstalled.
I think the only ones that has them by default are 1-2 of the EG's and the RGU, plus the CVO EG and CVO RGU.
