Just got an 08 FXDSE2 Dyna and have not noticed any heating problems at all.  Is this
heating common to all 110 motors?  Thanks, Rellik

Rellik,

First off, welcome to the site!  Glad you found us...   

  All 110's, in a completely stock configuration - run hot - because they come from the MOCO running a pretty lean fuel mixture.  Many have chosen to add some type of system to allow for a richer fuel mixture - such as a SERT or Power Commander or similiar product.

Dump all oil and replace with Amsoil synthetic Motorcycle oil SAE 20W-50. Problem solved...

Blame the Feds, air cooled engine that has to meet EPA standards, gonna be lean and hot. Not a MOCO apologist by any stretch, I just think they're caught between a rock and a hard place on this one.

Absolutely correct.  We are losing more of our freedoms every day to unconstitutional agencies like the EPA.  -Too bad that our top of the line new Harleys have to have radiators.  It's pure BS.

Nothing unconstitutional about it.  And I for one am very happy that some forward thinking people passed the Clean Air and Water acts that authorized that agency.  We can actually breathe the air and drink the water in most places these days, something that couldn't be taken for granted in the 60's and 70's in many parts of this country.  People in California can actually see the sky most days, as opposed to constant smog.  People like me with breathing issues can actually venture outside without risking serious health problems.  If you would prefer we not have those protections, I would like to recommend you take a trip to the industrial areas of China and see what this country would look like without the rules and regulations we have.  The fact that meeting emission standards has been such a chore for Harley but not many others is an indictment of the people running Harley, not the EPA. 

If anyone wants to keep their dinosaur Harley running cool, they can buy a simple set of fans that will keep air flowing over the heads when stopped or moving slowly.  They could also stop buying ever bigger V-twin engines, which generate more heat.  Harley has many choices they could make.  They have chosen to stick with a hundred year old design, and if customers want a hundred year old design, they will have to put up with a lot of stuff that a modern design would not subject them to.  As they say, it's a free country and you can choose to buy whatever you want.  But if you buy it and don't like how it runs or how poor the reliability is, blame the folks who built it and sold it to you, not an agency that just put the rules out there for everyone to meet and did not dictate how anyone had to get there.

The good news is that there is one hell of an aftermarket industry created by all this stuff.

[RayG]

Why would changing oil reduce the heat to a motor that is well documented as a very hot running motor.  There are things that can be done to reduce the heat but changing oil is way low on the list.  Problem Solved!  Really!

[MLCRISIS]

In the mean time while we bitch and moan, about our own EPA standards let's just go ahead and ship our coal to china. Just saw a huge load going out of Vancouver BC. I'm sure they will burn it clean.

[Steve_G]

I hope no one has illegally bypassed EPA rules by altering their air cleaner.  Or changing their cams.
Or changing their exhaust system.  Or modifying their fuel delivery system.  This would put more pollution in our air and cause respiratory issues for the phony people who just selectively support the fantastic EPA.  These people should just buy Gold Wings and suchlike.

Sorry I disagree with this as a resolve to the heat concerns.   Changing oil does not resolve a lean condition or the fact of the profile of the cam builds pressure and heat with little to no overlap.

Is it a better oil that I would agree with, but too cool the motor will take a tune and adding fuel or changing the cams with a cam that allows for more overlap and a tune like the 24d cam.

[JCZ]

Thanks Harry, for getting this thread back on topic.

And I agree, it's gonna take a hell of a lot more than a simple oil change to cool a 110" down.

  Another part of the equation no one seems to talk about much is the fuel we now get at the pumps. Almost all of it has some ethanol in it, as high as 13 % in Cdn. I believe its higher in some parts of the US.
While ethanol does raise the anti knock value slightly, it lower s the actual stoich value of the fuel.
Pure gasoline has a stoich value of 14.7, mixed fuels lower that to 14.2 or so.
In some parts of the country, and its becoming more commonplace is the oxygenators added, once again lowering the stoich value. A recent article from Burmingham AL, had a refinery guy telling the rider that their fuel had a stoich value of 13.9.
These fuels will make your ancient designed V twin run even hotter unless retuned to match the lower values. You might have to bring the actual mixture rates down to 13.5 to help cool the engine. It may also require some timing changes to accommodate the lower BTU's produced by these less efficient fuels.
 Harley, IMO is struggling to keep your V Twin on the market as it looks right now. At some point it will no longer be able to meet EPA, and I see that as happening very soon unless major changes are made to get engine temps under control. 
While you can modify your motors dramatically to get a cooler engine with all kinds of aftermarket tuning and parts, sooner or later, EPA will enforce the stds much more stringently. jm2cw  fwiw twinotter

Don't want to be a smart apple here,but rather than changing the Stoichiometric AFR,and investing in expensive internal mechanical fixes,there are a number of aftermarket permanent solutions available.The biggest consideration here has to be engine heat management,and the loss of lubricity in over heated degraded oil.In both cases,you can gain continuous cooling by using a twin fan set up mounted off the HD horn bracket(dropping CHT) producing a very desirable cylinder head temp change.There are a number of units available.The next and last item ,used in concert with a fan set is a fan assisted engine oil cooler.the effect of this combination is game changing.The unfortunate thing here,is that the MOCO could have resolved this problem easily while in CVO production,but their interest  didn't parallel that of the bewildered consumer,we CVO owners.

Been there done that. Wards fans,ultra cool fan assisted oil cooler, V&H x pipe , Rineharts and a tts Dyno tune.  Still on the boarder of being too hot.   On a really hot days I might see 270* sometimes which is getting close to too hot.  Usually stays in the 250* range which is ok.  I am considering a cam change.  I am also considering removing the lowers to get better air flow on the motor. I plan on keeping this bike for 10 years like the last one if the motor lasts that long.
