Your bike is twin cooled already. The addition of a fan is going to have little effect.
This is a myth. The only "cooling" the liquid does on a Twin Cooled bike is one loop around the exhaust ports. I have seen tests that show the actual engine temperature of twin cooled bikes gets hotter than the air cooled bikes at speed because of the lack of an oil cooler. When Harley says "twin cooled" they actually mean liquid (which it isn't really) and air. I've actually had dealership employees tell me it meant liquid and oil cooled. They thought the water pump was an oil cooler. Given this I can understand how folks could get confused.

These folks have done some testing that may be helpful if someone wants to try some things to cool down their bike.

I bought a set of the badass fanz have had them about a month. I can tell they do make some difference. Fans are nice quality. I wired them to a switch wire so they run all time. But they do have a switch on them to turn off. Would I buy them again probably so.

Hey MURPHCC1,

I have also been running Jason's fans for over 10 years now. First on my Street Glide, and now on my TriGlide.

They are still running strong, but I would like to know where you purchased a replacement fan for yours just in case one of mine craps out.

Thanks

I once read that Ward said he used fans from server power supplies - designed to be run 24/7 for years. Since they are potentially exposed to water, I never was sure if I believed the server origin, since most data centers have roofs and don’t have much weather to deal with…

They're water resistant and dustproof, but never had and issue riding in the rain.
This is where I got a replacement. Pretty sure that where Jason got them.

Out my HD cool flow on back in 2021. Have it set for automatic. This thing kicks on and off as needed.

It does indeed help.

Good to know! I have an account at DigiKey, they have great stuff! I have the Ward's, and so far have had no issues, but I know the day is a comin'...

Thanks!

Just in case you have to replace one.
It seems that the one that broke for me actually rotated inside the housing.
Breaking the wire at the housing.
Over time the torque of starting loosened it up.
Never really saw if Jason had some kind of stop in there to keep it from rotating

When you trim the outer square housing to fit in the round hole, make it tight, or secure it there so it doesn't rotate and screw up the wires.
