Duo64: aftermarket oil cooler?


Post by OneHandDuo » Wed Apr 17, 2019 11:58 am

Dear all,
my 1964 DuoGlide had an aftermarket oil cooler installed between the rising chassis tubes below the forward engine mount.

I was told the cooler had always been there since delivery 1964 to IRan, which is hard to believe seen the fact that under hard breaking, the oil cooler crashes into the front fender and made a considerable dent into the front fender (which was not the case when I got the bike). On the positive side, I have proof now the fender is metal ;-)

Question to the knowledgeable:
is the DuoGlide and derivatives prone to overheating in moderate climates? I live in Northern Europe, eventual stints to the Mediterranean are planned.
Is such a oil cooler a must? a good idea? a "why not"?
I don't like the bent fender and splintering lacquer and consider removing or - alternatively - relocating the cooler.
Thank you

A lot has been posted about oil coolers. Here in NW-Europe we don't need them in my opinion.

What is the reservoir's holding temperature in the oil tank?  Is it consistently above say about 220* Fahrenheit, then a cooler may be helpful.  If the temp does not exceed that figure, then no, do not run a cooler.  The oil needs to get hot enough to purge moisture and some other volatile contaminants.  On my project 1950 Panhead I removed the cooler in favor of a spin-on filter because that filter is working every ride, and the cooler was mostly unnecessary.  Now, you just need to figure some way to monitor the oil tank temperature.

I rode my stock 60 panhead and 75 shovel in the central Florida summers without a cooler. No issues. They cool off every hour when you stop for gas anyway!
