Any reason not to enable the rear cylinder cutoff?

Living in the northeast , I could probably do without the feature anyway.
After talking to a few people (hundreds) this summer , the only people that had a stall out or pop and stall at a traffic light had this feature enabled.
My bike had it disabled from the factory , that said , I enabled it at around 1000 miles.
I had my bike stall unexpectedly twice in the next 4000 miles (in traffic).
I have ridden the last 2000 miles (EITMS disabled) and never had it stall again.
In all fairness , the bike seemed to run perfect either way , just the stall was the difference.
My bike and the other 2 people that had this happen , were running bone stock bikes.
The one guy took off on a right hand turn at a light and went down with his wife on the back.
His local dealer said to leave it disabled , because they had seen it happen a few times with other bikes.
I think it's a great idea , especially for hot region riders , but I think there are a few bugs left in it's implementation .
Just my observations.

I leave mine enabled all year but then again our summer last almost 9 months.
Besides the smell the only other down side is you have remember to burp the throttle before taking off from a stop light or it is likely to bog down in the middle of the intersection! If you burp before you start moving, the rear cylinder comes to life and youre good to go!

ENGINE IDLE TEMPERATURE MANAGEMENT STRATEGY
A rider-activated rear cylinder cutout feature keeps the rider more comfortable by shutting down the rear cylinder during parade duty or idling situations.
Activated by rolling the throttle back and holding

Per MotorCycleUSA.com 2009 models: " Last year, H-D rerouted the exhaust under the frame away from the rider instead of its prior arrangement under the seat. It also has a rider-activated cylinder deactivation system that curtails heat when you’re stuck at idle. Roll the throttle grip forward for five seconds to engage the Engine Idle Temperature Management System, which in turn will stop fueling the rear cylinder. The cruise control indicator light will flash green to let you know it’s on. Give the bike a little throttle, and the cylinder will begin to fire normally."

Don't you guys read your manual?
It kicks on at like 287 degrees, and shuts off at 275 or something. The temp is read at the cylinder head.

I don't personally think there's any reason to disable the system with a stock bike. The only relatively consistent issue I've read about has involved the PC-V and that has already been mentioned. The one thing in this conversation that's surprised me is the number of folks who have complained about stalling. I don't know what mods these folks may have on their bikes. Mine is still box stock and the system works very well. I've had it activate many times so far, including in temps between 65 and 75 degrees. If you're riding slowly enough, long enough, the engine's going to heat up. That's just how it is, but mine has performed flawlessly. I've not noticed the odor issues but the cadence of the engine definitely changes when the rear cylinder cuts out. On the other end, touching the throttle any at all and it's back running on two. The transition has been almost seamless. If I didn't know what was going on, I might not notice.
FWIW!
