I like to ride at close to peak torque and under... Most big twin Harleys achieve peak torque at between 3000 and 3500....
where do you think peak torque is on a Metric sport bike???? Certainly pushing double that for some... or sounds like it anyway!!!!
Only Vibration will change... Maybe.

If one cylinder is 165 psi and the other is 100 psi, it would be kind of dumb to ignore that.
What's a twingle?
I found this but that is not what an Evo is.

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.

I would never reject my carb. That’s just mean ;-)

As the guys say, just run it as it is and don't worry about it. Cam, cam bearing, lifters, fix/replace the carb if needed, but gearing wise, you are better off running at the higher RPM. That's where the power is. As I've said before, I once left for Sturgis, 1K miles away, and lost the speedo sender before I got out of town. Just set the tach at 4k to 4200 in 5th gear and left it there. In Sturgis, I replaced the sender and sort of realized how fast I had been going. That explained why I was passing so many....
