Unless that oil cooler also includes cooling fans its just about useless when its needed most like for example when sitting still in traffic @ stoplights or when in slow moving traffic " DUE TO LACK OF AIRFLOW THRU THE COOLER IN THOSE COND " !
It's only when you get back up to a decent cruise speed where an oil cooler without cooling fans becomes effective @ cooling again & thats where an oil cooler with twin thermostatically controlled cooling fans kicks BUTT @ cooling the oil & motor sitting in traffic & or at slow road speed and also @ cruise speed too.
So an oil cooler with cooling fans has all bases covered when it comes to cooling the oil & motor sitting still in traffic or when @ cruise speed too.

From the FAQ page:
How is Mobil 1™ V-Twin 20W-50 motorcycle oil different from Mobil 1™ for passenger cars?
Mobil 1™ V-Twin 20W-50 fully synthetic motorcycle oil is designed for air-cooled, large-displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk-oil temperatures. As you know, a typical air-cooled V-twin's rear cylinder gets a lot hotter than the front cylinder – it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in your bike climbs rapidly. Above about 250 degrees Fahrenheit, conventional motor oil is going to break down. Mobil 1 V-Twin 20W-50 fully synthetic motorcycle oil is good to above 300 degrees Fahrenheit. Like Mobil 1 Racing™ 4T 10W-40, Mobil 1 V-Twin motorcycle oil has high levels of phosphorus/zinc and the same high-temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures. With Mobil 1 V-Twin motorcycle oil, you can go the full length of the manufacturer's recommended oil change intervals with ease.

Im not ready for that, dont feel it will do me much good. Most of my riding its moving interstate and moving local traffic, not many traffic jams.
Im just looking to upgrade a passive (no fan) device already on the bike which would be an upgrade to the existing oil cooler. This would be strictly to give a little more leeway on hot days and traffic. The cost right now is almost the same to slightly cheaper then Wards. But not about price for me, just about what I would like to do with the bike and a system that exists on the bike but can be beefed up.
If I wanted to, in the future I could always throw a switched fan on the cooler for the rare traffic conditions I might encounter.
Oil coolers are very effective cooling the oil which flows through bearings etc but will only buy you a short amount of time for actual engine cooling and then maybe about 5% more cooling for the actual engine temperature. Even if I elected to have fans, I would still want a simple plug and play 10 row cooler to replace my 6 row. Just makes sense in my hot climate.
BTW on my second year with the bike and it runs fine the way it is, just like anything, its more of a fun thing to me.

Attached is a pic of my ride last saturday in Montana. Everyone may think its only hot down south but it gets warm in the summer in Montana. Not every day but some days.
My bike, 12 CVO roadglide, 120R, woods cams, PV d&d borzilla and ventilator air cleaner on a 58Mm throttle. Last dyno was 148 ft lbs Tq and 139 HP.
My set up, 10 row jagg frame mounted cooler, extra 1.5 qt oil pan, wards fans.
Air temp guage is externally mounted so air temp is accurate as best i can make it. Oil temp is as it exits the cooler and ET is head temp from PV.
My target range for head temp is 235 to 255. Oil temp is 230 from engine 170 or less back to engine.
Bike performed flawlessly got 35 plus mpg and oil pressure was excellent all day.

Hey Dave,
Being you are from way up north I dont think I would give too much thought to it but for less then $300 you can add a HD oil cooler to the engine for the heck of it as a fun project.
With that said, 260 degrees at the high end is fine.
For Harley Rushmore Touring bikes of 2014 and later. HD states normal oil operating temp of 230 degrees. As you know all non water cooled Rushmore bikes with the 103 HO engine come with factory oil coolers.
I find the 230 degree Harley statement right in there with what I am experiencing with my 2014 Road King.
I have been watching my oil temp close to a year now in our super HOT SC summertime and I would say 230 degrees is average.
Meaning depending how hot and how fast I am riding it will range from the 210s to an all time high I just measured on one occasion of 264 degrees. The 264 was slow speed riding but surprisingly I find (for the most part) except for VERY heavy traffic my oil temps are higher at interstate speeds when air is Rushing through the cooler. 75 to 80 GPS speeds my oil will run 235 to 245.
Makes sense when you think about it, moving faster means burning more fuel and producing more horsepower = more heat.
I do want to install a larger cooler on my bike, because so much of our summers are daytime highs of 90 to 103 degrees and to a lessor extent for traffic.
If there are any companies reading this thread I wish to god some one would produce a SIMPLE, WELL PRICED, HIGH QUALITY, PLUG AND PLAY, TEN ROW oil cooler for owners of Harley Rushmore Touring bikes.
AS we know HD oil cooler is a HIGH quality 6 row cooler being I am in a hot part of the country during the spring and summers, I want that extra 4 rows that can be squeezed in for a 10 row cooler.
Since the Rushmore bikes already have a 6 row cooler and already HAVE the adapter on the engine I would just love a product where I can unbolt the 6 row cooler and oil lines and bolt on a 10 row cooler. I do not wish to buy an adapter I do not need.
Anyway, I think if you call Jagg directly that they will sell you one without an adapter and I most likely will go that route but it would be nice if I could just order one online labeled as Plug and Play. I mean how stupid simple could you get?
Upgrade your stock 6 row to a 10 row.
Maybe someone from China is reading this and there will be one on the market in a week on ebay but I rather buy American

(got that jagg and ultracool) *L* Heck I would have ordered one online Monday if it could have been to my house by my day off on Friday.

Osoyoos where i live is considered the hottest spot in Canada with June through Sept temperature well in excess of 100f many times - So yes heat can be an issue

No question a fan on a cooler is a good option but lets not forget, the largest needed demand for cooling oil is when the engine is running highway speeds.
Look at it this way, at idle, the engine is just lumping along, producing little to no horse power with no load at all and burning little fuel = less heat.
Once on the highway, the engine is generating much greater horsepower, burning much more fuel and under much, much, more load. This is where oil can cook if no cooler.
Im not saying a fan is a bad idea, I am saying a cooler is needed more then a fan as a first step for people who do not have a lot of traffic issues.
Also having a cooler doesnt cool the engine all that much, maybe you will knock the temp down 10 degrees. Other then spraying oil on the bottom of the pistons, it doesnt flow through the heads like a water cooled engine.
Also oil is not terribly efficient at transferring heat and unless one is going to put on a much larger cooler then a 6 or 10 row and go to something more like a water cooled engine size radiator the efficiency wont be there, in this case, for an air cooled engine, blow air across the fins is the best option if looking to contain engine temps and the fins are the reason and method of cooling the engine vs liquid. (yes, I know, Im rambling on again

Wards fans is selling a product and provides documentation.
Let me make clear I have no interest in Wards fans right now but I do commend companies that back up their sales with stats.
Wards docs show the difference in temps between the front and rear cylinder is less then 10%.

I am shocked that it can get that hot there but you are in the hottest area of a whole country.
