Problem is, there really isn't one made to fit a Dyna Screaming Eagle CVO bike-I was looking for one myself. Someting that would fit between the down tubes so I could mount a thermostatically operated fan on it (that would be my own fabrication-the fan)

I have often wondered why this could not be done. I did this with an external oil cooler mounted underneath a volkswagon van and it made a big difference. Much smaller fan for a Harley oil cooler -hmmm now if I could just remember where I bought that thermostatic switch... Any way let me know if you work on this - I like the idea much more than that fan where the horn is

I have looked into the idea of using a muffin fan on the cooler, but I couldn't find one that would hold up in the elements. I never found any that were sealed. All of the ones I found were all open between the blade and motor. I was afraid they would become disposable.

Speaking of oil coolers, I'm adding the Harley's Deluxe Oil Cooler to my Ultra. I purchased oil cooler and the chrome cover, both same as used on CVO's and need somone to confirm somthing here. Im almost positive the chrome cover is supposed to install 'under' the black flat mount rather then over. In other words the chrome cover should cover the mount, right? I can't get this to instal this way, it binds and looks sloopy and wont center with the voltage regulator. If I install the cover over the black mount it does not bind and the cover centers perfect with the voltage regulator but you can see the black bottom of the mount, which to me looks sloopy.
I know somone is going to say 'where is pictures' but darn, im at work.. maybe this evening

I removed mine to clean residual oil, gravel etc and asked the same question this year.  I think the chrome should cover the black on the bottom, but it was easier to do it the other way.  If I remember correctly, the consensus was whatever you feel ok with.

The chrome cover goes on top of the oil cooler mount, between the cooler and the plate. I agree it would look better under the plate, but it goes on top.

Adding the fan turns it into a Goldwing once the fan turns on and blows the air on your right leg.  At least a GW warms both legs when the fan turns on.

After 100 years,why do we still have this problem? Lets face it,an inline air cooled motor is probably the worst design on the planet.HD never claimed to be an engineering marvel.

What I have always wondered is why the two jugs have the same fin pattern.  It should be possible to determine how much shadow effect the rear jug gets from the front ,and how much additional fin surface area is required to compensate.  If the fins on the rear jug were a little bit longer than on the front that would not be very noticeable, and the two jugs would run about the same temperature which should improve performance and longevity.

The only reasons I can think of not to do this would be that it would not look exactly the same as it does now (we would get used to it), and it would cost a bit more to have 2 different jug designs.

So far I have had no heat related problems, and the bike has not felt uncomfortably warm... Of course I did not pick up the bike until late December!

It's cheaper. Both jugs are the same part number.

......and it smells like fried rice!!!!!!

Be extremely careful on the amount of space you use up between the down tubes. When we put my bike in the wind tunnel to try to alleviate the high speed wobble, we were amazed at the way air moves between the sown tubes and wraps around the motor. On a bagger the use of lowers helped in the air movement, but almost every variation of spoiler between the down tubes restricted the air flow around the motor.

A little suggestion....the lower you can mount the fan and cooler....the better

During the warmer weather, I ride 40 miles one way to work and if I dont leave the house at the right time, I hit rush hour traffic and the 110 gets very hot as you all know including the exhaust burning your right leg. So I did everything I could to cool her down for those type of conditions. Tuning her with a Race tuner, Dual exhaust so I could get rid of the cross over pipe and adding a FAN to help cool her down.

Thanks Hogasm, duly noted...back to the drawing board! I really don't want to resort to removing the "spoiler" to do the job, but with all the research I've been going through, it looks like the only alternative for an oil cooler on a Dyna. Maybe i'll just drink more beer...with topless women...

any chance of sharing video of your bike in the wind tunnel? that must have been cool!  also, i agree about placing a cooler between the front tubes-----at slower speeds (when you need it most) it becomes an oil heater! its very close to the headpipe. the better cooler mounts to the left tube on the outside.

Now you should do something for yourself...add the mid-frame heat shields which will pretty much keep the heat you still generate off of your inner thighs.  I noticed a BIG difference when I put them on my SEUC.
