It just seems unnecessary to me and looks terrible
If anything I have considered an oil cooler but fans on a dyna are silly.


I have been riding hd's in south texas my whole life and it is hot as f in the summer here

 

My understanding was the fans are more effective than the oil cooler and are a less invasive install. .no worrying about leaks. That's what has made me want them over the oil cooler.

 

^^^^+1. I've been riding Harley's since '74. I can't remember how many I've owned, but I clearly remember never needing to bolt some fugly crap like cooling fans on any of them. If you're overheating, get it tuned. Not only will it run cooler, it'll run better as well.

 

How much of the perceived need for these fans is rider comfort vs engine health?

My 88 spent 50k miles of it's life in the SoCal desert region and the PO reported some minor detonation in stop-n-go traffic only. He added a Jagg oil cooler and that solved his issue. It never had a problem while rolling.

That said, it is only a tiny 88. More cubes & power output equals more heat dissipation...

 

All I know is my tuned 110 can run up to around 300deg on the power vision engine temp readout in slow or stop and go. Where the 103 in my last low rider and probably my road glide will hang around 250. While the aluminum and steel in the engine are fine at that temp, even synthetic oil isn't happy at much hotter then that. I'd rather preserve the rest of my moving parts by cooling it down a little more. Now granted, I did install a Ultracool fan assisted oil cooler at the end of the season, so I haven't had the opportunity of testing the difference it makes in August, but in a year or two I'm probably moving south. So I'll take any additional cooling I can get when I eventually end up in Atlanta's miserable traffic...

 

Wow. I have a 107 in 1 of my bikes making 136/142, and it doesn't get that hot on a 100°+ day.

 

That moving..., or sitting in stop n go traffic for 45 min..., to a couple of hrs

Fortunately, I don't sit in stop and go for a couple of hours. About 30 minutes in a jam is tops. I couldn't live where I sat 2 hours in traffic. If you are doing that, you need water-cooled.

 

Appears West Texas does have some redeeming qualities

Every so often an idiot or two on 360 / 820 find a way to screw up an anvil

Then there's the never ending construction


Time to lane split / take the shoulder

What's wrong with flat land, no trees and high winds? Lol. I think the possible new lane splitting law would be a good thing. Until some redneck opens the truck door to spit... :-D
