Yea, OK, we all get it; you're a goram Jedi Master. Funny thing though, how you conveniently left out the actual ****ing solution here. Not actually a surprise, though.
Reducing the hottest part of the engine; now, how do us mere sad unwashed mortals, clueless posters, serfs, and retards actually do that?
Fans? Oil coolers? Better tuning? Magic pixie fairy dust? Hope and prayer? OR just use some hyperbole to make it all better?

Steve Cole owned you, just get over it.
And by the way,
Who needs entertainment when stooges like you two are here.
You two keep posting as well

My interpretation of Steve's response is simple. A tune helps, but it only delays the inevitable. A oil cooler helps but only when moving, unless a fan assisted unit is used. And the one Tincup doesn't want to hear (sorry Sir, but you know we disagree on this point) is that engine fans do help. Seems these are the things we've discussed that help the engine run cooler. Note, no mention of rider comfort, and since my 110 seems to be one of the hottest damn motors ever built on 2 wheels and I can tolarate the heat when idling, I don't care about rider comfort. I want my motor to last and run happy.
With my fan assisted oil cooler, my oil filter relo kit and my wards fans (on my LRS, LJ's on my Road Glide) my PV engine temp does NOT break 260 degs in the hottest summer days, when in the past I've seen the same gauge report +300. My oil temp, courtesy of my HD dipstick never breaks 260 either. My Red Line gives me that added piece of mind for hot oil temps.
Now the point I may be that all this may be unnecessary for a motor engineered to be hot. But it makes me happy so that's where I am.
Ignorance may be bliss

One thing to note is that the sensor is not screwed into the hottest part of the motor.. YOU can see a 20 to 40 degree spread between the intake side and exhaust side of the motor.. Try and IR heat gun sometime.
ET is the heat temp sensor.. They can track within 0 -20 easy. Some of it depends on the lifter flow to the heads..

When you say they can track 0-20 or a 20-40 difference, are you meaning that the temperature difference between the intake side of the head and the exhaust side of the head can vary by 20 - 30 degrees? Is this what I should see if I use a IR heat gun?
What do you mean about depending on lifter flow to the heads. Are you talking about the flow of oil to them? Do certain lifters flow more oil up to the heads than others? How can I tell how much oil my lifters are flowing up to the heads?

I don't have a IR heat gun, but I'm looking to to get one. I looked this weekend and found one at Northern Tools for <$30 and another one at Harbor Freight for <$30. Will either one of these work okay?

The 0 to 20 is oil temp versus read head temp with thermocouples (best way) and the 20-40 deg front to back head was measured with the Raytech. So yes you will see a difference in surface temps based on location. One thing to note is that IR guns read temps better on dark, flat colored surfaces. Light and shiny are not so good.
Lifters control the amount oil going to the heads. If you push a bunch of oil to the heads through the lifters the oil will heat up more.. Stock HD lifters are flow enough to heat the oil significantly. Auto lifters tend to flow less.

Go to amazon, you can get em much cheaper. I've got a couple Nubees, a Crampman, and a older Raytech.. NuBee and Raytech were closer..

Highest ever saw on my 05 Dyna was around 280-285 .. Since Added The SE AF Filter, V&H 2:1 Pro Pipe Andrews TW21's and Rejetted the Carb to a good A/F Fuel Ratio and Running Amsoil Pure Synthetic Have not seen it above 270 and Most of the time far less than that .. Not Saying has to be Amsoil, or my choice of going to Stage 2, but a Good 100% Synthetic Oil will drop the temp some, as well as the Right Tune for your Engine ..

You are probably better getting lifters that are for HDs but I've used both.. Oil temps will run hotter..
