Here is a thought for you: the last two issues of American Iron magazine has a running, in depth article about oil coolers. Before making your decision, read the articles. I have the premium oil cooler setup from Moco I installed a little over a year ago. It is not a bad cooler but I am going to be switching out to a Jagg this winter. You will benefit from having the proper oil cooler.

I think after reading the AI articles, it would be a good idea for all EPA bikes, to help control detonation. Otherwise, you can install a temp gauge where the air temp gauge is on the dash, or put on the LED dipstick, and keep an eye on oil temps. Keep in mind the oil in the engine is warmer than in the pan. I routinely push the button on the dipstick whenever I stop get off the bike after any longer ride. I've also been surprised at how long it actually takes for a Harley engine to get really warm--20 miles or more on a warm summer day.
My '06 with Stage One usually runs 220-230 max, but did have one 260 degree spike last fall when we had a warm day and I had already put on the fairing air deflectors and didn't have the vents open on my lowers.

Anyone else see the side bar in the article about the SE 110 engines? They apparently have had a problem with rear head gaskets blowing out. Don't they come from the factory with oil cooler already installed? The SE Ultra sitting at my dealer had one on.
Donny's opinion is that that engine should have much higher compression than its 9.3, but probably doesn't because of heat issues.

I did see that side bar about the SE 110. I don't know if the coolers are standard on the SE's from the Moco or dealer installed.

A good question actually. Usually about 1/2 qt extra to fill the cooler and lines.

Be sure to run some protection over the oil lines,I was very careful in how I routed the lines and two months later just happened to notice the one line had adhered it self to the frame rail.It seemed like it swelled some,protect those lines with some type of covering.
