That new cooler is nice, but unless you're riding in slow traffic (might not help here anyway) or excessive temps, it's not really needed. I ride all summer here in temps up to 110 degrees and my oil temp have never gotten above 225 at the oil bag of my '00 Fatboy. But, hey, if ya like it...get it. There's a lot of stuff on my bike that I don't need but can't live without. If it has a thermostat...can't hurt.
The humidity is arguable. Human are effected by humidity because we rely on evaporation for cooling. An engine on the other hand does not. 100% humidity will not effect an engine the same as a human.
A gauge is the first thing. Not knowing what is going on sucks. A thermostatically controlled cooler is the best bet over all if needed.

A oil cooler was the 1st mod I did to my TC.
Overcooling would only be a problem in very cold riding conditions. The T-stat only bypasses 70% on the H-D coolers, so it may be that a cover is the best thing for extrem cold riding condition.
A oil cooler may be the 1st best add-on to any Harley that will see hot weather riding. Some folk dont like them so the Mo. Co. made sure the TC could survive with out them but its been said that some tech's wanted TC's to have them from the factory.

Hey neighbor. RM I live in MA and my humble opinion is here in New England a oil cooler is a waste of money. I can see the point in the south and southwest where it get Africa hot but hell up here, mid 90's three days in a row is a big deal. As I watch the snow falling out my window.RMharleyman said:
I disagree. Overcooling occurs anytime where the oil does not reach a temperature high enough to evaporate all of the water trapped in the crankcase. This can happen on a 110 degree day, or a 10 degree day. You need to reach a high enough temperature range, for an certian period of time to flash off all of the water. At 210-220 degree's, this wil happen much faster as opposed to 180 degree's.Kags said:
Heat wise, I don't worry about an air cooled until well over 230 degree's.

It has been claimed by some that the TC88 original design included an oil cooler.
The temperature at the oil tank does not reflect the highest temp your oil sees.
Installaling a themostat will ensure your oil gets to 180 degrees F before the cooler is used.
My oil temp reached 245 degrees F without the cooler, in mild weather during normal city riding (not much traffic).
Your oil does not have to get to 212 F to vaporize moisture.
If you don't use an oil cooler, you might consider using synthetic oil if your oil runs hot.
I run a cooler, and use a cover over the cooler when it's cool outside...without the cover, in downtown traffic I still see about 235 degrees F when the ambient temp is 95 F, confirmed by two gauges. I don't like to see engines running too hot.

Folks,
You might want to check this out (confirmation, enlightenment, etc.)
No, it's not something about Zen LOL

I have one. I live in Hell. In Hell they come in handy. If you don't live in Hell you probably don't need one.
Now Purgetory is another subject. If you are there no longer than your warranty, don't worry about it. If you outlast your warranty then To Hell with it and go ahead and get one.
Welcome to Hous... ehhh Hell.

One thing I would dissagree with Don about is the statement no air means no cooling" A oil cooler will cool even in still not moving conditons. That statement is like saying " when you stop moving your motor has no cooling". We all no that the heat convexes off the motor at a light or stop sign. Same for a cooler. I think he was addressing a good place to mount the cooler rather than a low air flow place.RainRider said:

My oil changes have mostly been while I'm on the road somewhere so I'm kinda stuck with Harley oil. I use an oil cooler with thermostat and a Feuling oil pump. I do run lowers sometimes so I'm doing my best to help the engine stay cool.......
My oil cooler protects me from the snipers here in Maryland.
OK, just kidding, but I drove from Gettysburg last night back home and stopped along the side of the road to gas up, and with my Oil Cooler my oil was still 200 degrees plus.
My opinon, if ya get one with a Thermostat, you can't go wrong, plus they look good!

I was going to put an oil cooler on, but most of the people around don't use them. I am just going to put an oil temp gage in the fairing so I can keep an eye on it. I don't get stuck in traffic that often and the weather around here isn't that hot, but if I lived in hell or purgatory I would get one.
