Onedef1,

I have the wards fans on my 120r. They help. I also have the high capacity oil pan and a Jagg vertical 10 row oil cooler.

My 120r runs between 212 and 230 oil temp and around 250 head temp max as measured by my PV.

With the wards fans on i can keep the head temps below 250 easily even in stop and go traffic.

I believe based on my experience that keeping the 120r in a tight temp range aids performance and lets you get the best outcome. Ive got about 10k on my 120r, heat has not been a problem since i changed cams and valve springs at about 500 miles

 

I believe 230 degrees is considered to be normal operating temp for the twin cam 96" according to the MOCO.

Some guys think that is too high and some think it too low. There are a lot of latrine authorities out on these forums. Never a consensus on anything.
Personally, I have no problem with the 230 number, but I am absolutely positive that some will.

 

I've had the Wards fans on my 2012 Ultra Limited for about a year. I do notice the lower heat/bike running better when caught at slow speeds and stop an go traffic. For me it is awesome. When I'm on a trip and caught in stop an go traffic, I don't worry about melting down any more.

 

Kind of a loaded question, but, how were people taking the temperature and where were they measuring at? If you check your tuner you will get 1 number but if you use a digital laser point type thermometer you get another. Same goes with where the temperature is measured, if you shoot the pointer at the base of the heads or at the spark plug location, the numbers will be hugely different.
Wondering what the concensus is here?

 

The standard would be to use the engine head temp provided by the sensor to the ECM, anything else would have too many discrepancies. You could point an IR gun and get wildly different temps fractions of an inch apart.

 

These bikes were designed to be air cooled, and they don't give a damn about temperature. They're torture tested in Arizona where they're idled until they run out of gas.

Run synthetic oil. Change it every 5,000 miles. Stop worrying about it. Heat will not hurt your motor.

 

If you don't install a temperature gauge, you will never have a problem.

 

LOL!,yes air cooled HD's are designed to take the heat & wont explode if you dont address the excessive heat they generate esp in outside HHH summer heat.

But the fact reamins newer gen HD's or modded HD's are running hotter then ever which significantly reduces engine perf along with reducing rider comfort lvl at the same time too.

HMMM,do you think maybe thats why most bike mfgs water cool larger disp motors and why HD finally stepped up to the plate partially water cooling their lrg disp bikes with old school TC v-twins motors?

So the fact is unless you actually install a quality oil cooler with electric cooling fans along with wards cooling fans you guys making a joke out of even trying to cool the overheated air cooled HD's in summer heat actually have no idea what your talking about because you never did it,now thats funny!/LOL!!

So all you guys get thinking your air cooled TC V-twin HD motors are doing just fine without cooling help in summer heat can " be proud of all the benefits your getting from increased oil & engine temp in summer heat " which are as follows:

* OIL PRESSURE IS 10-12 PSI LOWER.(so you install hi perf oil pump or hvy dty spring trying to inc hot oilpressure)

* INCREASED VALVE TRAIN/LIFTER NOISE. (replace lifters & cams trying to quiet valvetrain)

* MOTOR IS MUCH MORE LIABLE TO DETONATE ON PREMIUM 93 OCTANE FUEL IN SUMMER HEAT WHEN UNDER A BIT MORE LOAD.
(often have to run more expensive prem 93 oct fuel in stock HD 9.2 comp motors to reduce & not always stop detonation/ping when HD states 91 octane fuel is all thats required for the lower 9.2 compression motors)

* MOTOR LOOSES MORE POWER/TRQ WHILE ALSO HAVING LESS RESPONSIVE SOGGY THROTTLE RESPONSE TOO.(thats fun!)

* MORE HEAT IS GIVEN OFF MOTOR TO RIDERS REDUCING RIDER COMFORT LVL. (thats fun too!)(install expensive tuner trying remap richer/dyno tune in an attempt to reduce engine tempo with mixed results as far as reducing engine temp go's)

* HOT STARTS LIKE POST FUELING UP ARE SLOWER/HARDER BECAUSE STARTER/BATTERY/MOTOR ARE ALL HEAT SOAKED/HIGHER TEMP. (some guys install aftermarket hi trq starters ,more expensive batteries & hi cap battery cables trying to correct hot start issues when quite often root cause was excessive heat especially with stock or mildly modded motors)

* SEALS (ESP VALVE SEALS) /GASKETS /THE PLASTIC OR TEFFLON MATERIAL RUBBING BLOCKS ON CAM & PRIM CHAIN TENSIONERS ARE MADE OF ARE BEING EXPOSED TO CONSIDERABLY MORE LONG TERM HEAT THAT CAN POSSIBLY LEAD TO SHORTER SRV'C LIFE OR WORSE YET THE OVERHEATED TENSIONER BLOCKS POSSIBLY SPLITTING/ CRACKING/BREAKING APART PREMATURELY IN SOME CASES TOO GETTING INTO OILING SYSTEM TRASHING THE MOTOR IN THE PROCESS DUE TO EXTREME HEAT DEGRADING THE PLASTIC OR TEFFLON MATERIAL THEY ARE MADE OF.)

So all you guys that dont think a lrg disp air cooled HD v-twin can benefit from additional cooling from AN oil cooler with cooling fans along with wards fans at the same time too can enjoy riding your HD's with all the lovely added benefits i stated above being totally pig headed and stubborn thinking you know better when have not ever tried both those cooling mods at the same time truly knowing nothing about the benefits of cooling our air cooled TC HD's in the 1st place.

Me on other hand have done it benefiting from installing the 2 cooling mods i stated above along with also having well over 4+ decades wrenching motors/bikes/cars under my belt to draw on giving me the experience to realize when a motor suffering a lot from excess heat issues in summer heat.

I experienced that 1st hand the 1st time i rode an air cooled HD in summer heat seeing & feeling 1st hand for myself HD's air cooled V-twin motor truly had excessive heat issues in spades in summer heat (esp in traffic or at slower road speeds) without cooling help like i stated above resulting in multiple ill/negative effects.

But post installing the 2 cooling systems at the same time reducing oil temp in my HD's motor 50+ deg F in summer heat i my HD no longer suffers from any of the ill effects i stated above due to excessive heat.

So since you obviously dont believe myself or other people posting here in hdforums that your avg are cooled TC HD motor has excessive heat issues in summer heat should take a couples ins to open & read whats in the the link i pasted below to read some of the many 1st hand testimonials of what HD riders had to say post installing an oil cooler with thermostatically controlled electric cooling fans on their HD's,they are happy campers!

" You can lead a hose to water but you can't make it drink "

Lord knows i tried to get you guys to realize you just might be mistaken on this heat thing,but i guess you just dont care to better protect your $10-15-20-25k+ investement along with significantly improving your overall riding experience at the same time too !/LOL!! (I " strongly/hjigher rec " installing Wards Cooling Fans at the same time you install an oil cooler with electric cooling fans too so they can work together collectively to create a high perf cooling team cooling team like i did on my bike that reduced oil temp 50+ deg f in summer heat resulting in multiple benfits right off the bat!)

Happy motoring in summer heat on your air cooled HD's that according to you guys are doing just fine without any cooling help where they are truly suffering i'll effects from excessive heat they generate!.

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

The word " Denial " & or old saying " head in the sand " comes to mind after reading statements like above here some guys are posting in this thread when it comes to excessive heat air cooled TC HD motors generate vs all the multiple benefits i got right off the bat when doing so/addressing the excessive heat my air cooled TC HD motor was producing that reduced oil temp 50+deg f in summer heat.

I cant believe there are more then just a few guys posting here that seem to be completely closed minded to things or think they know better when they in fact have never tried the 2 cooling mods at the same time on their bikes in summer heat to experience the benefits 1st hand for themselves before posting their completely incorrect opinions based on absolutely nothing because they never tried it & continue to argue the point when they have absolutely no experience at all with when it comes to cooling thier air cooled HD's.

I go by facts & not just opinion based on nothing like some guys here because they never tried it which is just BS.

Enough said!

You people are all crazy. 99% of harley riders are not readers of this forum, they dont heavily mod their bikes because they dont obsess over heat, etc, and their bikes are not all burning up by the side of the road.

Stop fussing and ride.
