To the OP of this thread... We have some seeious tinkers and overall gear heads who post about their builds on here. If I was so incluned t, I could learn a great deal from them.
But I enjoy reading about their mods rsther than chance it my self.
So stick around. And let nature take its course

I had an 80" evo in my FXR and crossed the desert in the middle of the night going from CA to AZ doing about 95 the whole time so I was up around 4300-4500 if I remember right for about 3 tanks of gas. She took it like a champ no issues at all other than every 100 miles we had to stop for gas. Guys in Phoenix must have heard me from LA she was screaming so loud haha. I cruise on the freeway at 80 too. I was told by my local "old timer" haha, that the evo loves being in that 3000-4500 range and to keep it rapped up there

I think you will be fine running all day without redlining it. I just did 1,656 miles in three days from Phoenix to Alpine, TX and back. Had to run Hwy I-10 more than I wanted at 80mph @ 3,750rpm, running full to empty tank several times. Only upgrade is an EV-13 cam and I run an oil cooler. Other than that, my bike is bone stock and currently at 86,000 miles.

Not adding anything you haven't heard already but ill add most people tend to lug their motors when taking about a Harley especially experienced riders coming from metric bikes. They're just not the same.

Close to my 30/70 on my twink andif I’m not cruisin at 80 in 6th which is the norm around here on the HWY, then I’m doin 70 in 5th and bike loves it!
I don’t think there’s much difference other than vibtations with any given model or year.

When I first got my FLHTC, I was reluctant to wind it up. Eventually I realized that it is just fine running at 3,500+ all day long.

It is worth noting that if your concern is based on the perception that the engine is screaming, there is a somewhat unexpected cure for that.
Change the cam to an Andrew's EV27. While in there change the cam bearing.
Install a free flowing air cleaner.
Reject the carburetor.
Install a dynatek ignition module.
These changes will produce more power and it will have an easier time at the higher speeds.
If you pull the heads, install Tye .030" Comeaux gaskets. Check the heads for flatness on a glass surface. If they are not flat or are warped, get them milled slightly.
Before doing anything, check your compression in each cylinder. Not only are you looking for adequate PSI, you are also looking for significant differences between the two cylinders.
