So the radiators are no longer to be used as water radiators but would now be oil coolers?  If that is the actual summary than my impression is you are trying to re-invent the wheel and making it much more difficult in the process.

Even assuming the passages and fins in the radiators are adequate to be good coolers and that they would hold up in that role capturing them inside the lower fairings would still hurt their effect.  Using the water pump is also entirely and unnecessarily redundant.

The water pump is needed to move the water.  The engine already has an oil pump to move the oil.  Just get a couple of good JEGs high capacity coolers.  They're specific to this task to begin with.  Mount them vertically on the frame and plump the whole thing in series.  This has been done before.  It works.  It is likely to work better than what is being suggested.  And it's using parts designed for the task.

Just my 2 cents worth.

the new twin cooled bike are not new idea it was taken from sportster and its also running in exhaust ports put with oil .

since the 110ci come out thare is heating assio  and its bean almost 10 year and evrry one speak about exhaust and tuning
that's all ?? its seams no one like to use his brain anymore .or my be your country cold enught but not mine

im searching for used lowers with radiators and fan and I well try and update you with resolts .

Kaween,

It looks like you have done all the research and came here to see who amongst us has pursued such a modification. As you can tell by now, most of us here stick with what we are used to, a good tune, external oil cooler with fan assist, and fans to cool the heads. It's not that we don't use our brains anymore, we just stick with what has given us good and steady results. To be honest, you probably won't find too many members willing to submit their CVO to be a test subject for new, fresh but untried and untested ideas like yours.

So please, by all means, go ahead and start your modification project on your bike. Many here will be interested to see how it progresses. Take photos, document the changes, and post the results. Please post up long term results too.

Good Luck

And yes, the lowers with radiators and fans will bolt right onto the crash bar on your bike.

Hd didn't continue with oil cooling for reasons, the coefficient of btu removal being a large factor. The glycol/water mixture works better for a lot of reasons including that fact. Changes to the fan delta temp. and turn on point can improve the factory setup. All possible, I believe, in TTS,software.

I agree with you if I have 14 up , but im speaking about 2011 . and I don't know if any  tuning device allowed you to change fan opraiting temp ,

I know little about water ethileen and glycool but all that these nothing if you don't remove the metal oxeed wich is storing temp in water , sorry I cant explaine  with the right words in English but I hope you got my point .

thanks for your info

Kaween I think you have an interesting concept here, but maybe making it too complicated. Why not install too  "oil coolers" one in each lower,with silent fans, and plumb in these to any existing cooler. From the oil filter to say the right lower cooler, then to the already there HD centre cooler, from there to the left lower cooler, then back to oil pump.
I'm just thinking there are 100's of style and shape of cooler in the auto world, finding two to fit into the lowers with fans should be fairly easy. The fans could be controlled automatically thru temp sensors or a simple  on/off switch. As long as there is an adequate air outlet for the heated to escape the lowers, it should be of benefit.
The other thing to note here is that HD are notoriously lean running to conform to EPA regs, most will run very much cooler with a suitable tuner like TTS or DV and a proper dyno tuning to get AFR into areas suited an air cooled engine. 200-220 degree is perfectly normal operating oil temp.
Myself I can't imagine running a HD or any other brand with lowers in the conditions you experience in India.
Good luck in your quest for a cool running bike.  twinotter

Kaween, if you already have the Jagg 10 row with fans and the Wards fans you have pretty much one of the best cooling combo's already. As already said the normal twin cam motor runs average 220-230 degrees.

Ask Fullsac Steve what normal operating temperature is.

200-220 is oil temp or cylinder head temp ?? from the end of this month until med of November evrry one storing his bike in all gcc countries like saudia and Bahrain and Kuwait and dubie and Qatar .

im Arabic from kingdom of Bahrain not indian

thanks for your inpot

the wards fan make the rear cylinder not shot down in night that's right . (in night ) but not effect the oil temp at all .

the jagg 10 row if you compared to the original one then no change cuz thear is a lot of thing blocked the air , so the fan is use les
and I even run the cooler without thermostat and still the oil temp exeed 270 f in night and at speed of 60 to 70 mile it stuck at 245 - 250 .f

Kaween,

Maybe I missed it, but are you measuring oil temperature with the dip stick thermometer, or an in dash gauge wired to a plug in the oil pan?

And yes, the Wards fans move hot air off the heads preventing the engine from going into skip fire mode. It does not cool the oil.

[kaween]

Ask Fullsac Steve what normal operating temperature is.

with all recpect to Steve (fullsac ) and he know about his jop  no dupt about it but don't know nothing about my country climent (weather) or the type of fuel octane that we use .

why all that negitve  reply do I say something wrong ??

the idea is I don't feel im alive if I don't make something new atleest one evry year and its jast happened this time that I like to share as long evry body are asking about the same thing (heat ) then all what hear is (don't) .
any way thanks

yes my friend I have dip stick digital gage from Harley and i don't know how to loging by cell phone otherways i well send so many picture

the fan move the tempreture from cliynder heads to your legs and magin that my friend with 85% to 90% humidity 365 days ??

thanks

Disagreement or questioning isn't negativity.  Without being negative about playing with any new idea it is still the case that ideas just won't pan out.  I can speak to this from first hand experience.

Something else to keep in mind is that we're talking about an air cooled engine.  A very old fashioned air cooled engine at that.  And an air cooled engine that is now pushed to close to its extremes in fuel/air mixture and displacement versus power output with those extremes being designed for an intended use that is primarily an American audience.  In other words at some point you have to quite fairly start to wonder if Manama (Bahrain rather than Panama I'm guessing) is simply an environment in which the stretch from late May through early September is just commonly outside the bike's design specifications?  So you ride at night?

I still think that if you want to add extra coolers you're better off doing it with open air oil coolers and their intended cooling fans rather than extra complicated pumped and plumbed systems that were never intended to be oil coolers to begin with.  Sometimes the enemy of perfectly good enough (or as good as its going to get) is the attempt to make it better or more complicated.  That's not negative toward you or a lack of interest in what you're describing.  Just a fair analysis of what the Design Brief for your project would likely suggest.
