During the Summer months, it gets pretty hot down here in Florida and riding my Vmax and seeing the engine temperature creep towards the red line always had me on edge. I flushed the system, added additives to the coolant that helped a bit but I wanted the fan to come on sooner.
Some folks out there rig a switch to manually turn the fan on but I wanted something that would automatically take care of it. So, I found a thermal switch that is specifically made for the Vmax and it works like a charm. The bike runs cooler and the fan comes on earlier now and the engine temperature never gets anywhere near the red line any more.
