Hi Kevin,Most have said they are not having any issues with high oil temps on their Twin Cool's.
The heat in the heads seems well taken care of by the OEM coolant/radiators/fans. Although I'm still running the Wards fans on my wethead, and just feel better keeping the temps down with the fans in slow going.
However, on the oil, for me, it is a problem not having an oil cooler...I like my oil to not go over 230* as a rule, and not over 250* in the exceptional circumstances. For me, on my 2014, with the way I ride, and places I ride, I have seen the oil flirting with 300*. I've tried one oil cooler that I am not happy with, will be installing a Jagg in a couple of months, and believe that will do the trick.
On my '11 TG the Jagg Wideline did a great job.

Hi Kevin,
Have you figured out where to put the oil cooler? I'm also interested.
I am going to try the Wideline 10 Row off the left downtube (no thermostat), right behind the lower fairing vent. It will have to be at a bit of an angle, but with the vent open, it should have good air flow across it. I believe that will do the job. If it does not, I will put one under the body, between the left rear wheel and the rear pulley. Will have to make a bracket for it, and probably an air scoop.
Kevin
Kevin that your oil is best at 230 degrees!! I use to think that if mine got much over 180 - 190 degrees that I should be concerned. My H-D Technician (personal friend) advised me that a good oil temp was 230 degrees and he was concerned that most owners continually try to keep their oil too cool for evaporation to take place.![]()

Maybe you'll have better luck, I'm running the 10 row wideline on my 06. Only way I could have kept the lower would have been to tuck the cooler tight to the engine which looked goofy. If you would go under the body you might want to keep something to bypass the cooler with, underneath is a good place for a rock strike. I had a cooler on an 05 Classic mounted in front of the regulator, took a rock hit and leaked oil like a pig. For a cooler under the trike you might want to look at the Oil Bud cooler https://harleyoilcoolers.com/, they say their virtually indestructible.

I hope to get a good angle off the downtube...it seems like I will be able to, but if not, I will go under the body with a scoop, so the cooler will (hopefully) not be terribly vulnerable to rocks. But like you say, keep a hose and some hose clamps with me in case I need to bypass it.
Below is a copy and paste from another thread....I have an Oil Bud, I had high hopes for it...but it just is not doing the job for me.
btw, I now have 4000 miles with the scoops and they are still there.
***********************************
As I noted months ago in this thread, I have not been satisfied with how much the Oil Bud oil cooler actually cools down the oil. I have not taken the time to remove the Oil Bud and replace it with a Jagg oil cooler.
However, the other day I did a little experiment.
I took a funnel, cut it in half (and did a few little fitment cuts) and then attached the two halves to the frame, underneath the water pump cover. The theory was that they would scoop air and push it across the oil bud.
It is a jerry-rig for sure, but I was happy to see it lowered the oil temps a solid 10 degrees, so that is giving me a solid 25 degree total drop out of the Oil Bud. Not nearly as much as I expected, but better than a poke in the eye with a sharp stick.
I do not see this as a long term fix, and the funnel halves are the lowest point now, so they may possibly get ripped/knocked off at some point, but until I take the time to remove the Oil Bud and decide where to put a Jagg cooler, it is what I am going to be running.
Here's a pic-

It should be noted that on bikes with no water pump assembly and shroud, I have seen the Oil Bud deliver impressive drops in oil temps, as it should for the impressive price. However, my experience with the waterheads has been less than satisfactory, and it is understandable, the pump & shroud are blocking the flow of air over the unit, whereas with no pump and shroud the unit is directly in the wind.

Interesting, it makes sense, hope you can get a favorable angle on the downtube.
Thank you, me too. The pic of the angle on your 06 is not one I'll be happy with. Hopefully the Lowers are a bit further forward on the 14 TG and it will work. I'll know in about a month.
