TOO HOT (question 2)

Doc, I recently bought a 2004 FLH and I love the bike except for the heat that it generates on hot days. I have seen the Baker sump that you spoke of recently but have also seen that Harley-Davidson has an electric fan that goes where the horn is fitted. My question is, do these fans work and are they reliable? A few people have told me that the fans are like computer fans and are not up to the vibrations and weather conditions. Lanale engineering also has a fan that they boast about but I‘ve read bad reviews. Any light that you could shed on these fans would be appreciated.

There are a number of ways to approach the heat issue and I guess the more you implement the better off you will be. The Baker Plus 1½ oil pan is a good option, though not a cheap one, and the genuine Harley-Davidson parade fan is a pretty sturdy unit that US cop bikes have fitted as standard, I believe.

I can tell you from personal experience that they do help somewhat. I have not encountered the Lanale unit but, like you, have read mixed reports.

Currently, I’m carrying out testing on both the Ultra Cool twin fan oil cooler system and also the JIMS ForceFlow Cylinder Head Cooler, which forces the heat away from your engine by pushing high velocity air through the cylinder fin pack in a wide flow pattern, directed at the head gasket surface. The unit is powered by a cooling fan that was designed to cool brakes in NASCAR. Watch this space for the results.
