Yesterday I was riding and hit some traffic, my 15 CVO Street Glide was running at 357 Temp...when the hell does the cooling start? Or am I wrong in thinking that the liquid cooled heads does not generally keep the overall bike cool just the heads?

If so then damn was I wrong about this bike in thinking it was never gonna over heat on me!

ZVO...what you really need are liquid cooled exhaust pipes!! In all seriousness, your exhausts are what is retaining the heat more then the motor. The combination of the two creates hot, hot. Change your exhaust to catless pipes and 20/30 % of the heat will be gone. Liquid cooled heats cool about the same or a little better then bikes with oil coolers on them. Jmo. I have owned both.

What temp hit that high?  Was not sure from your statement.  Oil?  Head temp?

If it is oil, the highest I ever saw was 240 degrees.

Oil temp was 357 on my road glide in traffic with just an oil cooler I was never higher than 238

The hottest part of the engine is the heads, and the hottest part of the heads is the area around the exhaust port.  That is the area that is cooled by the liquid coolant on a Twin Cooled bike.  If you tap into the data stream and read the head temperature as reported to the ECM by the sensor in the front cylinder head, I'd be willing to bet the temperature on a properly working Twin Cooled bike will be significantly lower than the head temp on one of the air cooled bikes, especially in long periods of slow or no air movement over the engine. 

Where exactly are you measuring 357°, and what are you using to measure it?

I have the dipstick with the temp gauge in the oil reservoir.

WOW that is to high, there must be something wrong with your gauge. Here in Sydney on a summers day 42 deg C about 115F,  My 1450 dyna oil temp never goes over 95C / 205F even in stop start traffic. it has an oil cooler kit fitted.

My guess would be the gauge is malfunctioning.

The Harley digital temperature dipsticks are notorious for being inaccurate. If you're concerned with the operating temp you could use an infrared temp "gun" to check your cylinder and head temps.

 Does the "infotainment" system provide a readout of the engine temp as seen by the twin cooling sensors on the '15's?

[ZVO]

Sorry I was mistaken it was 257
The readout on the screen only shows Air Temp, oil PsI, and wether or not EITMD is enabled or disabled.

I kept the oil temp dipstick from my 2010 limited with Andrews 57 cam. On 2010 I was about 240 most time. On this 2015 CVO Limited I run about 10-15 degrees warmer! Same headpipes on both, VH Power duals, which has no cat and is 2:1:2 for nice pipe.

SEPRT download too. Just are hot at 110 compared to 103 I was guessing.

gotcha...I will be installing a High Cap oil pan during my 1000 mile service so that should cool things down even further.

[bakon]

Like to put an oil cooler on it. Ran oil cooler since 2000 on all touring bikes and never had one problem

[grc]

257°F oil temperature is perfectly fine and absolutely no reason for alarm.  Use a good quality synthetic oil and don't worry about it.

Dont waste your money, it'll just take a little longer for the oil to reach that tempature. Replace the stock header and mufflers and add a fuel tuner. Additionally, I've read numerous posts on this fourm which state the 255 cams contribute to the heat. Down the road if it continues to bother you a cam change will help as well.

As Jerry mentioned above a good synthethic oil goes a long way.
