do they make a fan set up for the '07 yet. My bike gets hot quick in town. Curious if this works on the '07 as the site old offers up to '06 models. http://www.harley-davidson.com/gma/g...bmLocale=en_US

I have been told it really does not reduce the engine temp. It is mainly for the comfort of the rider.

The IDS is the mod that increases rider comfort - and all the other wonderful things previously described....

The heat managemant download does work, and it isn't all that noticeable when the rear cylinder kicks in & out.
Whathappens is the fuel and spark to the rear cylinder are shut off via the ECM when the temp reaches a certain point and the engine is at idle- like in a traffic jam on a hot day. With the cylinder not firing it is producing no heat, soengineheat is reduced.That cylinderalsoacts like a big air pump- sucking in cool air & pumping out hot air, further cooling the engine. At the same time, the mixture to the front cylinder is richened- which also aids in cooling. Hit the throttle and the ECM turns the fuel & spark on to the rear cylinder again and off you go.
I haven't had the d/l done on my bike yet, but I've ridden two bikes that have.
I plan to have it done on mine soon as I get around to it...

Is this something specific to the new models. Mine 04 Road King just doesn't get that damn hot.

Engine heat is greatly reduced when you install true duals, sounds good too.

The P&A book lists a black and alsoa chrome fan that replaces the cow bell horn.
The purpose is to reduce heat in "prades" and other slow moving applications.
Works of an Air Temperature Sensor that is installed in the A/C.
In conjunction with the "Parade" download, this helps cool slow moving or stop and go ridden bikes.

Pre '07's had less displacement, lower compression ratio, and different fuel mapping in the ECM than '07 & later models, thus less heat.
