Australia’s leading H-D magazine reports on a long trip by their premier writer: “…Cool-Master puts out more cooling power for those who want the best of the best. Make no mistake, both of Hammerhead’s patented dual fan cooling systems deliver at least twice as much cooling punch than any other product sold.”

SHOVEL HEAT
Hey Doc, it seems you are a brave man to consider riding to Darwin from down south on a Shovelhead powered bike, no matter who built it. I’ve had Shovels and they always ran bloody hot. Have you taken any special steps to counter this in your technical wisdom?
– Whitey
Whitey, in my testing of the original Love Jugs where, on a very hot day, I let my Road Glide idle in the driveway next to my wife Jane’s idling Switchback the temperature difference was so impressive it sold me on the product. Now as you say, Shovels run hot and big cube Shovels run even hotter. So it was a no-brainer when it came time to ride up to Darwin and back that I should have some Love Jugs fitted. So I put the call out to Steve of Love Jugs who shipped me out their latest model, the Cool Master (love-jugs.com/new-cool-master). As with the original Love Jugs the Cool-Master blows a strong stream of air across the hottest part of the engine’s cooling fins. This boosts the cooling function of the fins whether you are riding along or stuck in stop and go traffic. And this new model is even more powerful than the original. And yes, we did hit particularly hot riding conditions on a number of occasions where I was very glad that the Cool-Master was on board. From experience on two different Harleys I can highly recommend this product.
I contacted Hammerhead Engineering for a Cool-Master their newest modeHere is what they say about it.
“The new model has a number of innovations that will help even more Harley owners tame the heat beast they are riding. The heat generated by a V-Twin air-cooled engine can approach 500 degrees in stop and go traffic. Even lesser, but still high temperatures can destroy the lubricating capabilities of the engine oil, and ruin many an engine, to say nothing of destroying what should be a pleasurable day on the road for riders and their passengers. The only way to safely and effectively cool down a high temperature air-cooled engine is to consistently run a powerful stream of air across the hottest part of the engine’s cooling fins to dramatically lower the heat. The newly developed Cool-Master puts out more cooling power for those who want the best of the best. Make no mistake, both of Hammerhead’s patented dual fan cooling systems deliver at least twice as much cooling punch than any other product sold.”
And I can tell you that in the heat of the Northern Territory I was very glad I had them fitted!
