I ride a 2007 Road King, and live in Japan, where we get very hot summers. I worry about how hot my bike is getting when riding in summer and have thought about fitting an oil cooler. I know that cooler oil is better, but can anyone tell my what cooler oil actually does for the bike? I'm sure it'll extend engine life but are there any performance advantages? I'm planning on doing a cam upgrade next year, and thinking of adding a Fueling oil pump and maybe a Fueling Cam Support Plate at the same time, but I'd like to know what the advantages of cooler oil are before spending the extra cash. Any thoughts and advice most welcome.
