Blah, Blah, Blah. If you don't believe in oil coolers . . . good for you.
Condensates my a$$.
Who set those oil temp specs anyway? Oh, I know . . . the MOCO. Imagine that.
Just getting a little bit tired of you chiming in every time a person mentions oil coolers.
Having posted this . . . I feel better.
Yes, I have an oil cooler on my bike for good reason.

And lastly, realizing that the MOCO has an extremely sophisticated engine research and development program, I would have to favor their specs and recommendations over any individuals "backyard" engineering.

A perfect example of a situation where an oil cooler is needed.

Just as an FYI. American Iron magazine has had several articles on oil coolers over the past month or so. Bottom line from their view was that every twin cam should have an oil cooler. They also ran a lot of testing and such... coming up with the conclusion that the Jagg 10-row cooler was better than the HD 8-row cooler. If you take the time to read the articles, not sure how you could ever defend not installing an oil cooler. I'm planning that as one of my over-the-winter projects this year. The articles convinced me!

I'm convinced enough that I have one on order. And I'll use synthetic oil too. (I'll save telling which one for an "oil thread". :-)
For me it was a toss up between the Jagg and HD one. I went with the HD. I know Jagg claims theirs has less pressure drop because the hot (thinner) oil is routed through the filter first, then is bypassed to their turbulated cooler. But the HD cooler does come with a thermostat so not until the oil is hot is it diverted to their turbulated cooler before filtering.

What I like most about having the HD Oil Cooler or any cooler is that you can actually see a drop in oil temp when you start moving again after stop and go. Max temp on 90 degree days are 220 if that and I see a quick 5 degree drop on the oil temp gauge if temps do rise.
Before installing a cooler once the oil temps rose it was impossible to reduce temps even after increasing speed/air flow. The only way to reduce temps was to shut down and let it cool.
I strongly recommend oil coolers.

I just installed a HD Premium Oil Cooler last weekend. I have a 95" motor with 204 cams. My bike would run from 225 to 245 in the winter and 250 to 270 in the summer. Way too hot. And yes, I have always used Synthetic oil. I also ride about 12,000 miles a year. After reading the article in AIM I decided that an Oil Cooler was a good Idea to help extend the life of my motor. After riding 200 miles with the new oil cooler last weekend the hottest my bike got (in 85 degree weather)was 215!!!Much better.
Harley Davidson will have to make the same decision Porsche did back in 1998 and go water cooled very soon to meet the ever increasing EPA emissions standards. So I want to protect and preserve my air cooled Twin Cam.
The installation was simple but they should have mentioned the very odd 7/16 size Hex nut required!

Makes a LOT of difference.
