Same reason why i disabled mine. bike sounds like crap and i dont feel any benefit as far as decreasing heat on myself.

 

...and then for the contrary opinion, I have my enabled. But, when I have my Wards fans on it does not come on.

The fact that 1/2 of the engine becomes an air pump...wouldn't reduce the oil temp, and consequently the overall engine temp?

 

I keep mine enabled, and it seems to help.

 

Ehh the infamous parade mode. My first tuner a PCV didn't like it worth a crap pulling away on one cylinder at a intersection caused it to sputter. Never seen any real prove it doesn't help motor in high heat.

 

Contrary to some I like to have EITMS enabled.
I like the decreased heat for my comfort - also it can only be doing good to the engine not having it heat up so much.

 

What a lot of folks fail to think about, is the rear cylinder is still creating heat from friction. I understand there is no combustion. That's how we used to warm up our semi trailer mounted 2000hp 16v149 Frac pumps in Northern Michigan in the winter time, shut the fuel off to them, and since they had a hydraulic starter off the tractor, pull the lever and let them roll over for 10 seconds, stop and let the heat soak for 20 seconds, repeat for about 5 minutes, then turn the fuel on and she'll fire. I see it as a placebo thought up by HD that a lot of folks swallowed.

There is no way to quantify.

 

Mine was enabled before the stage 1, it was definitely an odd sensation and sound when it activated. Now that it is disabled I am thinking it will stay that way. Maybe if in a situation of oh Hell no stop and semi-go traffic, then I might enable. So for now it stays disabled.

 

I leave mine disabled, 72,000 miles in Texas summers and no problems with it that way.

 

An infrared thermometer gun pointed at rear cylinder head / exhaust header port is all that is needed to quantify. Its intent is not to reduce oil temp or heat caused by friction but simply the heat caused by combustion which has the largest impact on head and exhaust port temps.

 

If your rear cylinder is generating perceptible heat from friction, you might have some other problems. Internal combustion temperature is about 800C. That a lot of heat...
