I have a 2005 FatBoy Harley. In May of 2010 I installed a larger engine in the bike. In warm weather the bike was constantly over heating going into parade mode when simply setting waiting for traffic signals to change. I installed an UltaCool oil cooler on the bike and it actually lowered the oil temp. by 60 degrees eliminating the problem. I just purchased a 2015 Road King with a factory 103 engine with all the same problems of over heating that the previous bike had. Installed an UltaCool oil cooler on the bike and it once again eliminated the problem. Absolutely no bull, Great Cooler
