I had issues with overheating when I first got my bike, so I installed a temp gauge. Shortly after that I switched to HD full synthetic oil, and my temps dropped a full 20 degrees, and I've never had a problem since. I also considered a cooler, but shitcanned the idea. The first summer I had my bike I got it so hot I started blowing oil out of the exhaust on several occasions. I do think that pro-one cooler is the shit, very clean looking and a little smaller than the Big Dog cooler, plus the temp gauge built in. I'd say chrome it, I think you're splitting hairs. How much less is it really gonna cool?
