RE: Which oil cooler to buy?
After looking all over the internet on oil coolers (OCD), I have decided to do the "road bar" type of cooler. There is another forum that discusses this, but I plan to use the Jagg oil filter adapter w/ thermostat.With this method there are no long lines back to the tank, just the two short ones to each end of the bars (take them off and have them drilled and tapped for the hose fitting; use compressed air to blow out any metal particles, clean with alcohol, hook up the lines; add 1 (one) extra quart of oil) and bingo, instant oil cooler. Oil temp on a 90 degree day @ 70 mph, should stay abt. 210. Sunday, at 95 deg @ 70 mph on interstate 75,temp was 250, so this would be a welcome cooler. Just keep people away from the bars, i.e. KIDS.

Do any of you guys have specific part numbers and such and some good directions for doing this. I have heard of people doing this but havent been able to see any of the specifics on it. Thanks in advance for input.

I am a factory trained Harley mechanic, and have 35 years expierance. Please notice H-D does not put coolers on as O.E.M. equipment. They use to offer on as an accessorie, but don't anymore.
That is because they don't work, and the extra plumbing makes the oil pump work harder.
Most high oil temp problems occur at slow/ stop and go/in town speeds. Air cooled engines need air moving over them to carry away the heat. So do oil coolers. No air flow....no cool.
When I was in AZ. years ago at the factory service school, all the locals ran a straight 60 wt. or even a 70 wt. oil.
Where I live in WA. state, it gets into the 90s/100s in the summer. I run H-D straight 60. The factory service manual recommends this for temps over 80 degrees or so. Get rid of that 20/50, unless you only want to ride at night.

Harley P/N 26155-07 Premium Oil Cooler Kit. The item description says "Fits '07 Touring models. Stock on '07 FLHTCUSE."
(They also sell a model for 99-06 models as well.)
I'm also a mechanic by profession and I disagree that oil coolers do not work. While they do work best when air is moving across them, as long as the ambient air around them is a lower temperature than the cooler itself it will release heat even when still. Also, when moving, more heat will be removed by the engine fins and the oil cooler than by just the engine fins alone, so the engine will cool down more in stop & go traffic with the cooler than without.
