I've owned Shovelheads, Evolutions, T/C 88's. T/C 96's and a T/C 110. (I somehow missed the 103?).

On the stock engines I believe that the biggest heat (felt) increase was when the T/C 96 was introduced. My wife bought her '08 Heritage (coming from an Evolution) and she said "something" has to be done about the engine heat!
With new V&H exhaust system, a tuner along with a dyno-tune, a set of mid-frame Kuryakyn heat shields, and fork wind deflectors she was happy.

My friend bought a new '10 Ultra and he complained from "Day One" about the excessive heat on his RH foot and ankle (and coming from and EVO RK it was a real shock).
He continued to ride it and in late '12 and after I got my new 110 and had the Rinehart XT True Duals installed with a tuner and a dyno-tune, he took my bike and decide it was time to do something about his situation but by that time it was a little too late.
When the dealer removed his exhaust system to replace it, they discovered that the heat had taken it's toll and they decided to basically replace the upper end.
He asked about upgrading it with 103 parts and all he had to do was to pay any difference in prices so he now has a bigger, newer, cooler running engine and our MPG's are nearly identical.

He also added an oil cooler to his bike, and we both have the Wards Fan Kits.

One more thing that I would highly recommend to anyone that rides in hot and/or humid conditions is the H-D "Circulator" seat and backrest pads.
They help keep your butt and back dry and IMHO are well worth the cost.

 

I think those fans should be the first mod to a new bike, especially for us that ride in hot states. They can easily be taken off during the cooler months of the year for those that are not big on fans hanging there. At least they're on the low side when parked. Back them up with an oil cooler and the heat has no choice but go down. Both make life better for rider AND the engine.

 

OP---2016 Road Glide Ultra is all stock with the Catalytic Converter removed. If you like
the way the Ultra runs now, and don't plan to do anymore upgrades, your in luck. Go to
www.nightrider.com or www.dkcustomproducts.com and check out the FL-ViED-10, that
is an inexpensive fuel enriching device. The FL-Vied-10 are adjustable, I belive it adjust
the Air Fuel Ratio from 14:3.1 to 13:9.1. The FL-Vied-10 are plug and play, they are also
color coded to match stock plugins. Do it after your oil change, if you go to a dealership.

Xieds! Enrich your bike's AFR and it'll run cooler. Installs in less than 10 minutes, and I got mine off Amazon for $86. I went with just the basic xied, and they change your AFR from 14:7-1 to 13:8-1 in closed loop. Makes a world of difference in the heat, and my bike runs much better. Oh, yeah, my bike is all stock - airbox and exhaust.

 

=================================================

My 09 FLHTCU with basically stock 96" ran hot as heck in summer cond esp when in traffic & or when in slow moving traffic too.

I corrected that situation by installing Wards cooling fans(basically same as Love Jugs " Mighty Mite" cooling fans) along with an Ultracool oil cooler with twin elec cooling fans both at the same time for max cooling effort which lowered oil temp up to 50 deg f in summer heat.

THAT DID THE TRICK!

No more excessive heat coming from the motor hitting the riders,no more detonation on HD's rec 91 octane fuel for a stock 96" TC motor,oil pressure in summer heat was improved/increased by approx 10-12psi @ idle & cruise too,valve train now reamins quiet,hot starts like for example post fueling up are now easier/faster due to motor-starter-battery not being heat soaked anymore along with motor now retaining the pwr/trq & throttle response it used to always loose in summer heat prior to installing the 2 cooling mods that collectively together reduced oil temp up to 50deg f.

Installing the 2 cooling mods that reduced oil temp up to 50deg f in summer heat made my bike a totally different more enjoyable machine to ride at all times in all temp above 70-75deg & especially when riding in 90-95+deg f summer heat

And also keep in mind it's not only the oils job to lubricate the motor,it's job is to also remove/reduce heat from an air cooled or semi water/oil cooled HD v-twin motor.

So when the oil temp was reduced up to 50deg f in summer after i installed the 2 cooling mods overall engine temp was significantly reduced @ the same time too.

If your bike has a stock oil cooler thats not fan assisted its cooling efficiency is great reduced when sitting still in traffic or when at slow road speed due to lack of ample airflow thru the oil cooler when it's needed most which is where a fan assisted oil cooled literally kicks butt with it comes to cooling the oil & motor in the process on an HD.

BTW,the wards fans were easy to install,as for the oil cooler,it was not complicated or real hard to install either but was more involved because it had more too it.

It took me approx 5.5-6hrs to install the cooling fans & then the fan assisted oil cooler inc setup & then later cleaning up at the end of the job too.

A pro thats installed the same 2 cooling mods before would likely be able to do the same job a bit quicker then the 5.5-6hrs it took me to do the job.

1 more thing,after installing the 2 above mentioned cooling mods i then installed Xied adjustable enrichment resistors that corrected a lean surge issue,improved idle while making throttle response a bit crisper too which was great that resulted in a minimal 1-1.5mpg reduction/loss.

I found the 50% enrichment setting on the Xied's to work best for my 09 HD's mostly stock 96" TC motor.

The Xieds didnt seem to reduce overall engine,exhaust or oil temp on my HD which didnt surprise me due to the 2 cooling mods i had already installed on the bike,but without the cooling mods may have been a diff story.
