I had an old 550-4 back in the day, two into ones with no baffles. I could drown out any Harley with it. I still have it parked next to the Shovelhead. Bottom line, though, If you don’t want to cook your mill, ya gotta keep it cool, and air-cooled in 120 degree heat probably won’t do so well—especially if it idles any length of time.

Max Friz

And Carlo Guzzi

.....just might argue that point.

(But I won't.)

I’ll be on my own turf for my part.

No cooling issues, here.

[and I have an oil cooler on the down tubes]

Modern miracles.
