Hi again, all

Driving an 05 FLHTCUI (new to me). I noticed early on that, while stuck in downtown traffic (stop and go, heavy emphasis on the stop), my engine would heat, and then seem to really overheat. After checking around hereabouts, it seems like it may be one of those EFI re-map things (anyone got a good link or forum thread that would explain this in great detail? I'm still learning) to get the engine to run a little richer. (I also saw a thread concerning replacing either the cover for or the entire air filter--"getting rid of the football"--and think that might help too.)

(Putting it this way: on temperate days, the engine puts out enough heat that I have to stand up to avoid at least feeling like I'm burning my biscuits. The other day, driving around town in 50-degree temperatures, I got back to work with a couple of sweat bands on my pants where my legs overhang the engine. TODAY, driving in to work [on the highway!] in 40-degree temps and in my snuggies, I was feeling enough heat to make my legs sweat again. How's this going to work when we hit summer?)

I wondered if I might be able to take a couple of old PC cooling fans and just hang them in the front containers (and my biggest concern then was figuring out the electrical system). Then I read a couple of dozen threads here concerning add-on cooling fans and oil coolers.

The bad thing is, I'm having about zero luck finding any links to such systems (or the folks who sell them), either here or on Google. I don't doubt there are links lurking around here somewhere, but... Anyone got any solid recommendations on the fan coolers? The oil coolers? The ease with which I might be able to hook 'em up myself? <most_important>Who sells them?</most_important>

Really was kind of frustrated to find my first Harley was baking me alive, until I saw how many other people have had the same problem. Pity there's not an OEM water-cooling system that could be added, but fans and/or the oil cooler are far better than nothing, if I can just find them somewhere.

Thanks loads, all. I'm learning a lot from reading and questioning around here.

There are others here who know a lot more than me, but if you put a fan on the engine where do you think the heat is going to go? Oil coolers are a good thing and I would recommend one, but they do their most good while out on the road, in stop and go traffic they don't do much. Slip-On mufflers, a free breathing intake (K&N, Screamin Eagle, or Arlen Ness) and then a fuel management system with a good tuning would do the most good. I had my 08 dynoed after installing all that stuff.

Any bike is going to get hot in city traffic. I had a 96 Yamaha Royal Star, liquid cooled that would burn the inside of my legs when riding in city traffic, but that V-4 was a wider engine the a Harley. Heat shields might help some, but the best you can hope for a some reduction in heat, as long as its running its gonna put some out.

 

There is a fan out there that plugs in in place of the horn and is supposed to work very well. It provides airflow in stop and go traffic.

 

Fatten up the air fuel ratio with a stage 1 air cleaner and remap. Air cleaner about 135.00 remap about 180.00.......
The oil cooler is great but not much help in stop n go traffic. It does add a bit more oil capacity and allows a little more time in the tank for the oil to cool. Part # 26082-05B $298.95

Fan Kit...will kick on when engine temps reach ??????degrees. blows from the horn side to the right side between the jugs. Mounts in place of the horn and the horn is relocated. Part # 91550-00C $379.95

These are all H-D parts

 

Fixed the oven baking temps with a Thundermax Autotune from Zippers with another air cleaner. Like night and day, at a long light or in traffic.

 

ther are all kinds of mixed answers, I have a 2007 flht if you think yourbike is hot try a 07 or 08 with the lean condition .my answer was a oil cooler when moveing ,and a lenale fan when traffic hits .also did the stage 1 from harley ,download ,pipes air cleaner . the fan you can see it on ebay .

 

lol, move north, I dont even notice any heat on my new '08 FLHTC

 

its so hot up here in Idaho (in the 20s) that I'm hugging the engine for heat.

 

I have an '03 Ultra. Although your model has vents in the lowers, here is my policy. Early spring (usually around March/April) I take the lowers off the bike and don't put them back on until sometime in Nov (in fact I just put them back on). I never have an overheating problem with the bike or my legs with this method. I found this out the hard way, after almost getting killed at Bike Week about 3 years ago. The bike sitting in traffic would overheat the bike and myself and then it would just turn off in the worst places, like in the middle of an intersection or while making a turn in traffic. I would have to turn off the ignition wait 10 seconds and start it back up. After doing this several times on my first day down there, I rode it finally to the HD dealership in Daytona. The service manager just smiled and told me that I was the 5th person that day to have the same problem. He told me to go back to the motel and remove the lowers and the problem would be solved. He said the issue was the engine management system on the front cylinder would overheat and just shut down the engine to protect it and that was normal. I followed his advice and have been back to BW every year since and have never had this issue again. I am a firm believer that the lowers should only be used in the winter months and off all other times. Jerry in Chattanooga, TN

 

There is good inforamtion in all of the above posts. Harley has a Fan that is normally used on Bikes that are involved in Escort/Parade Duty. As Stated it replaces the Cow bell and requires the horn to be relocated.

You can and should add an oil cooler like the Jagg or HD Deluxe system.

A Fuel management system that richens the lean condition of the bike will also cool the rie down.

You can go to Ture Duals to get the "hot" spot out from under your right leg/thigh.

You can also get the "parade" download from your dealer that will shut down the spark and fuel to the rear cylinder when the bike is idling in a parade/traffic jam.

Good Luck
