Jeffnvegas - works fine on a Softail (heritage). I have mine installed on a deluxe with no issues. Since the Coil cover is forward on the Heritage, you just need to "re-shape"/re-run the plug wires to give a better "view" for the air to *** across the heads. Jason included a picture in his response of my install.
If you have any questions whatsoever, post them to this thread or just PM me.
Mine is a 88 so my experience will be limited to that engine. I do have a pretty lean tune on mine and the fans make sugstantial difference when below 55 mph. Before the fans, I would see 300F front CHT (hence the Crotch Cooler) when stalled in Houston traffic. After the Fans, I never see over 265F (it stabilized at this on the Freeway at speed yesterday) now and most of the time it runs around 245 between traffic lights when running sub 45mph. I do have an oil cooler so I'm not sure how much that might be affecting the results. The above temps are the latest numbers I got yesterday when it was 100F outside Air Temp and after running 75 mph (and occasionally a bit higher) to keep up with Freeway traffic.
Very much recommended!!!!

My first long distance ride since installing the cooling fans on my SG will be the 27 thru the 30th of this month. Riding from central Texas to Ft.Sill Okla to see my daughter graduate AIT. I know the fans will perform well, can't wait to hit Dallas traffic! (Just to give the fans a work out 
)

I have the head bolt covers on mine. Jason warned me that the fans' effectiveness might be reduced as a result. All I know is that those darn fans push A LOT of heat out the right side of my engine.
I did 1100 miles last Thursday - yesterday, in all sorts of riding conditions, and the fans really seemed to move the heat. I don't have temperature gauges, so take my experience for what it's worth. I'm considering removing the covers....hate to lose any chrome, but it'll be worth it to take better care of the engine.

Dyna install
2010 Dyna Wide Glide install PICs. I set my buddy up to try these out, its my original test set. Just had to adjust the plug wires and the keeper a little bit, works like a champ.

Since I announced the "new" fans, I have received several requests to exchange the systems I just shipped for the upcoming improved model. I cannot take back all the systems I just sold to exchange for the "new" fans. My warranty and guarantee is for the system as I sold it at that time, in its original and advertised state, if your only issue with the system is that you want the "new" fans because they are better, that doesn't qualify as grounds for a return. I apologize that I made an improvement after you purchased your system.
As I've said before I want my customers happy so here is what I can do; at a less critical later time, when things slow down a little for me such as this coming winter, I can provide a fan exchange service for those who want to upgrade, I can do this at a very reasonable cost, but I just can't exchange all the fans for free on all the systems I just sold. The best I can do is to do the work at no cost to the customer, but I have to charge for the new fans.
Its Funny how everyone loved the original system until they found out about a new fan.

Ahhhhhhhhh!
Got to ride and relax a little today. No parts to work on so I rode about half way back with my buddy who visited this weekend, got to ride about 300 miles today. It was much more pleasurable than riding to "test" systems. Now then as a casual rider and user of the system, I have a very different opinion of the system. Its freakin' awesome! It works better just using it to ride than it does when testing, because it's not being heated up to 300F+ and then cooled back down. From a cold start heading out on the road, I went over 1 hour straight with the cruise locked on 60MPH, rear head hovered between 240F-250F depending on wich way the wind was blowing from. I didn't want to turn the ride into a testing session, but how could I resist. I remember someone posted they observed a cooling benefit at 70MPH, so I tried it, and 80MPH. At 70MPH the rear head hovered aroun8 270F, and at 80 MPH it hovered around 280F, basically I saw about a 30 degree drop from what I would see without the head fans at theses speeds. Keep in mind these are my bike results so they may be different from your results. A reminder my bike has the 5 speed so I generally turn more RPMs than the 6 speeds, so I'm making more cumulative heat, and I have extended the lean cruise stoich sector of my map out to 3250 RPMs, and my oil cooler fan was still disabled. I think this system is good enough for now, if it hasn't already achieved maximum cooling potential. I didn't test it at 90 MPH today because I didn't set the speed switch high enough, but I think it probably still has some benefit at 90, and 80 will cover most riders most of the time. I'm not saying I won't continue to seek improvement, but I'm not so sure there is much more to be had.
