I'm in a situation where I have to take the 07 heritage softail to work for commute. I live in the inner city melbourne area and my journey consists of a lot of stop \ start bumper to bumper traffic. I estimate my average speed would be not much more than 10kmh.  7 km trip - 35 minutes. 

So things are getting very hot under the seat and both thighs uncomfortably warm. 

I'm looking at cost effective ways to dissipate some of that heat, to increase comfort and engine longevity. 

Ive researched oil coolers, oil coolers + fans, and jim cooling fans but not sure any of that would offer best bang for buck. Especially as I'm looking in excess of $1500. 

I'm thinking of getting a couple of computer server cabinet fans, cobbled up to see whether that offers any benefit before I splash $$$ on something permanent. 

Unless there are some other options out there which I'm willing to entertain?

I do come across bikes as old as that are still 100% bone stock with no stage 1 tune often the only change is noisy slip on mufflers.

Best bang for the bucks "tuning" wise are XiED wires that go into the O2 sensor wires, plug and play. Find them on www.Nightrider.com

Best bang for the bucks oil cooler wise is the heatsink type that push over the stock OEM oil filter (that's what I have used since 2008). They can be hard to find now tho' as the maker departed this earth. Called an "oil filter cooler collar".

Any plumbed in oil cooler system is way dearer, and at low speeds don't flow enough air. Heatsink type better there.

Haven't tested yet due to all the bloody rain and now cleaning up from the Cyclone but I've just added these to the Night Train. Should see a drop in oil temp.
