The new Harley Milwaukee 8 motor throws off a lot less heat than previous motor. Water cooled heads and better exhaust scavenging

How much is a lot less, what is the temp diffetence. I'd like to see the temps when you're in traffic, which is usually daily for me. In order to cool the heads you have to keep the lowers on, which restricts airflow to the motor where if you took the lowest off, increasing the airflow, you would cool the engine without all the plumbing.Originally Posted by Az Wingrider

Those water cooled heads were badly needed due to the massive heat generated from running a lean enough mixture to meet current emissions standards. I heard that the rear cylinder ran so hot that the NHTSA was investigating complaints about burns on the legs of passengers, and H-D compensated for the heat by deactivating the rear cylinder when idling.
The F6B's twin side radiator design handles heat better than any motorcycle I've owned. The way the heat exits on the sides keeps much of it off of your legs. It was a challenge for the stylists to work with those radiators. The fins don't look bad on GL1800s, but on the 1800 Valkyries the radiators gave the bike a strange appearance and surely didn't help it sell.
You could well be right, but aesthetics are at least somewhat subjective, and I love the look of the newer valks, especially from the seat. It's the ergos I could never warm to.

Aesthetics are definitely subjective. I liked the looks of the Rune and thought it was the best looking GL1800 Honda ever built. Others hated it. It sure didn't look comfortable however.
