Installed on my '14 FLHTK this winter. No ride experience yet. Waiting for salt & ice/snow to disappear. Buddy installed it on his K model based on my recommendation & he's used it. Says it works great. It's a manual on/off on my bike but I think I'll be able to figure when to use it & when to shut it off.

I started with pic 5. Installed pic 2 behind pic 1. The second one is installed in the horn cover. That cools the intake. The other one takes the header heat and blows it out the back.
Very noticable on hot days. Work great

Does it turn on and off automatic at a certain speed or do you have to turn it on and off manually? If you can turn it off and on manually when you want, I wonder is you can wire in an accessory switch in the stock switch bank with an AUX switch?

I first noticed this fan pop up on H-D.com when it came out. I really REALLY want one on my Ultra. But I have issues with the install.
First, it utilizes the same plug as my motolights.
Second, I believe it installs where my alloy-art stabilizer lives.
Neither of these are coming off, so.... not for me, I guess.
