Did this for a living. You bought an extended service agreement. It covers parts and labor for failed parts. Then there is a prepaid maintenance plan.

love jugs
it says right on my contract, 5 year extended warranty. So if you did that for a living I guess thats why you dont do it any more because you didn't know what you were talking about. Bedsides I dont care what you want to call it. i know what it is

do love jugs work
I am getting a lot of static from people about my theory on love jugs so i phoned my mechanic today and asked for an explanation on why he thought love jugs may have contributed for my Free wheeler motor to be destroyed by heat. This is what he explained to me and it makes sense to me so i believe him and not go on any more about it.
Explanation as well as i can.
The heat temperature sensor does more than just regulate the rear cylinder shut off, it also adjusts the timing when a certain temperature is reached and if the temperature gets too hot it will shut the motor down. The love jugs blow air on the sensor fooling it into thinking the motor is cooler than it realy is so the heat just keeps building until a failure eventually happens. It may take a while for this to happen. On my bike i didn't start to have trouble until around the 50,000 mile mark, by 65,000 miles my motor was finished.
He said for example if you have a gas furnace with a heat exchanger in it and take the thermostat off the wall and rewire it into the refrigerator the thermostat will think its cold in the house so it will turn the furnace on. Since the thermostat is in the fridge the furnace will never shut off and the heat exchanger will eventually get so hot it will burn out. As he said it may take a while but it will burn out quicker than normal.
This makes perfect sense to me and is what i believe could have happened so i will say no more about it and never again use love jugs. If you want to use Love jugs go ahead it makes no difference to me

Actually a Mighty Mite is a Jeep used by the US Military. Hope they checked before using that name.

The logic here is faulty. How long he has been pulling his customer's leg(s) is of no consequence. So the heat sensor has nothing to do with heat management on my 14 Limited
1. Heat management..EITMS only comes on at idle when ambient air temp is above some number (80??), not when head temp is above some number (on 2014 twin cooled Ultra Limited anyway).
2. can be disabled by the owner with simple hand throttle movements. If it is so critical to engine survival, why does Harley let us turn it off?
3. If your engine was destroyed by heat, because the EITMS was fooled into never running, how long did you let your bike idle (the only time EITMS comes on), with your love jugs fans running? My Limited has been caught in heavy traffic for several hours, in 90 degree heat, and although it got really hot, it never failed, and that was before love jugs.
4. Some other factor ruined your motor, and your mechanic either wanted to save you some embarrassment, or just wanted to blame love jugs because it's not a HD product.
5. Was your bike under warranty? Did they fix your bike?
6. I'll bet you let them do all your work, including oil changes...
Yes, I am a bit skeptical.
I got these for a specific reason, they come off with one bolt. Wired to a quick disconnect. I will run them when I think they will benefit me, like across Death Valley. And during Rolling to Remember (Rolling Thunder replacement).

may fool the temp sensor some but in city stop and go traffic my hot leg tells me it's doing what I want it to do. I'll be having lunch in Palm
Springs tomorrow and when I hit the first stop light my fan goes on. Along with that forget extended oil changes - mine gets 1500 - 2K max
as even synthetic turns to junk when your limp mode kicks in. Imho.

I like the DK heat test - guys wearing a black long sleeved jacket & its 89 degrees out....LOL

This could be easily tested by putting an oil temp sensor on the engine, and running with and without the love jugs. If the temps were the same, then, as your mechanic thinks, they do nothing to help, but if the temps ARE lower, then they actually DO cool the engine, which should eliminate that as a possible cause of the engine failure. I believe that this video appears to demonstrate that the temperature of the metal of the cylinders (at least on the outside) are "reduced":
Now, IF you have both, an oil cooler and the love jugs, that should eliminate the overheating issue entirely.

love jugs
IF the love jugs were ONLY cooling the sensor, then I could understand that, but since they are ALSO cooling the cylinders by "dissipating" the heat, blowing it away from the cylinders, so that they should keep them cooler, and the overall engine temps should be lower.

This would seem to indicate that your mechanic is not completely correct. Because of this, I might be suspicious of something else as the cause of the engine failure, and not solely blame the love jugs.

Also I just watched the video posted above. The way that person is using that heat gun that far away from the engine is totally useless. The heat gun needs to be at no more than two inches away from the heat source they are testing to be accurate. That far away just the breeze coming off the love jugs would give a false reading causing it to be much lower than it actually is. I ran a gas plant with numerous compressors on it for ten years. We had the best trainers available as each compressor was in excess of a million dollars and temps had to be checked accurately
