seriously do those fans work well and its seems like a lot of coin for them. ebay seems to be full of greedy people.

  in the heat of the summer I can turn my Mighty Mite fans on to blow thru the tunnels on the heads on my 124"...and it will drop the oil temps very quickly on my bike. It will stabilize the oil temp to right around 205- 210* with them on. With them off...I could see north of 225- 235* degree temps. Now I'm talking about 90* plus days with the bike good and heat soaked and getting caught at a long traffic light, or some serious stop and go traffic for me to see the 225* plus temps with the fans off. Once I notice my oil temp up into the 220* range...on goes the fan switch.
  So to answer your question are they worth the money...I'd say yes. I can tell you this...I will put them on every bike I own from now on after seeing how well they work.

Fans very in price depending on quality from nylon bearings to ceramic ball bearing,  water proof to non, heat resistant ect. Five Dollars to a hundred just for one, and that is just for one. That doesn't include any wiring or any mounts, guards, production.
And yes they work.

I have been on the fence about these fans, which one to buy. Mighty mites or the JIMS. Not much out there on the JIMS. Some of the reviews on the JIMS seemed like once you bought them there was no support or warranty if there was a problem. Anybody have any feedback on the JIMS fan?

I also have the Mighty mites, but on a Road King so cant provide any quantitative data as far as oil temps. I will say the motor doesn't seem as angry in those stop/go circumstances. We all know that feeling when when it's wanting to scream "enough is enough". That is a thing of the past for my bike. 

From what I understand, the fans have little to no effect at highway speeds. I flick em on just when I see fit.

I have a Baker oil pan along with these fans. I checked my oil two days ago after 4000 miles and it looked damned near like it was just poured from the bottle. In a 117" with around 11:1 comp.

I have Mighty might's on my 1995 FLHTC with an Ultima 120" motor. It bakes it's self without the cooling fans on , really makes a huge difference in stop and go traffic . Well worth the money . Also raises the comfort level a bit by not cooking your legs as bad. High power , high compression motors build heat very quickly, these fans help immensely.

Yes, the fans work.   Makes a huge difference in stop and go traffic. 

 I bought a set of the mighty mite I fans and yes it seems to drop the oil temp several degrees ,  I first noticed how much the fans helped on the 13 road glide with the 143 . Temps would climb very quickly and I would turn on the fan and that stopped and cooled down . I bought a set of mighty mites and installed them I believe this spring on the street glide. They worked well how ever yesterday I noticed on the way home after a few hours on riding that the temps were going up so I had to slow down . This is two up and hot .  Got home and checked the fans . The front fan has stopped working , damn . I hope the fan  can be repaired . My experiences  were similar to Rays on the temp . I would not want to ride the bike in the Texas heat with out them

Not sure if any one is interested but I called Tuesday and talked to a fellow about the cooling fans and he did not even blink I guess he simply asked for my address and said I send you another set . Please send back the set to see what happened . I did order a different mount that goes to the frame and remove the horn mount . Suppose to help the fans live longer . Probably so .

I bought Wards fans some years ago. I now have them on my M8. They work well and look the part. I think wards' is now owned by 'love jugs'.

Good to hear....for my 2 cents service is insurmountable!

   that is excellent customer service right there for you!   

Cheaper and better engineering to fix the problem at source.  Decrease the AFRs and the heads will not get so hot. Bike will run better too. No need for fans or bigger oil pans then.

  you apparently don't have a clue making the statement you just did. 
The fans help to cool the engine bringing down oil temperatures to an acceptable level for me. My bike is tuned very good and I can watch at least a 20* drop in oil temps with the fans turned on. My bike runs great without the fans...the fans are just an added bonus to keep the heat in check when I hit stop and go traffic.

Air cooled engine standing still in stop and go traffic. How much fuel do I add to cool it down?

I figured out a long time ago that even a small amount of air across the heads will do more than even the biggest/best oil cooler.

Sunny Jim,

How do you know this? I ask because I too have a set of Wards fans and love them. However, should they crap out, will Love Juggs repair/replace them?

Doubt it. Different companies

Correct. There was some talk that Love Jugs pilfered the Wards design, and Ward quit making them.

Not very much at all.  Just take the AFR to high 13s at that rev range.

I just ordered a set of Love Jugs Mighty Mites and the frame mount kit. I will report after install.

I'm pretty sure the love jugs were first, I remember when he was developing them over on the other forum.  Then there is this.

I'm not sure if there was a law suit but now wards appears to be gone and the new jugs are very similar to the wards design.

Well I do know a little but bow to your opinion -  but please do think about it.  Heat comes from the cylinder heads.  Leaner the AFR higher the temperature.  If you think this is not the case then don't read further😜.  Reduce the heat generated as opposed to cooling the heat kinda makes sense.  Sure cooling air over the heads will cool the temps. Not rocket science but start with a lower temp and you don't need to  force cool with an expensive accessory.

If your bike different that's great.  Always interesting to learn about braking rules of physics.  If your AFRs are in the 14s and your uk ride in hot weather around town etc (some stationary) a lot the bike will appreciate some low 13s at those Revs But let's not argue and fall out over the topic. Fans are "cool"

Seriously! An air cold engine sitting still? No amount of fuel will cool it off, you need air movement.

Seriously the fuel doesn't cool it - but richer AFR means it generates less heat.
