Yeah...the sound of day-glo bees swarming will no doubt throw the fear of God into them.
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.
