Im gonna look into these fans. backordered though

 

Does my 2010 Road King have this feature? My bike has stage III 103" big bore so would it still have work?

 

I'm in Texas an on my way to work this morning, at every light I stopped at (about 3) after a 14 mile highway ride, mine immediately kicked into single cylinder mode. Air temp was showing 85 degrees ( and trust me that is cool for us this time of year).

To me it is aggravating as well as I don't like the loping mode the engine goes into on the sindle cylinder. So if Harley says its for comfort (which I will look into for myself) I may consider turning mine off as I see no different in heat coming off of engine in or out of single cylinder mode. My two cents worth.

 

If it's based on the front cylinder temp, then how does turning off the rear cylinder protect the motor? The front cylinder is still pumping and not cooling down any.......I don't quite buy what it is helping (as far as protection or cooling of the overall engine). But that is just my opinion, not saying you are wrong, just trying to understand the logic.

 

seems like something they did, that they thought we would think works better than it does

 

Before I did a stage 1, it would come on at every light after the bike is warmed up....even in low 70's. it has not come on once since.

When it is engaged, the rear cylinder supposedly blows air on the front cylinder cooling it down. How much it actually works......your guess is as good as mine.

 

hah, funny guy. read your owner's manual. softails have eitms too

what? and how is it supposed to do that? what happens is that there is no fire in the rear cylinder, so the rear cylinder acts as an air pump, cooling down the rear cylinder, which is supposed to translate to a cooler feeling by the operator since you are sitting over the rear cylinder.

The air temp ain't what matters. I guarantee your cylinder heads aren't near 85 degrees. Your engine has control explosions of gas, compression caused by a spark. The engine creates the heat. It doesn't matter much the temperature of surrounding air that matters its the movement of the air that removes the heat from the cylinder that matters.

The rear cylinder doesn't get as much air as the front cylinder so that's why they shut that cylinder down.
