My bike is a 1992 FXR with a 127 CI Ultima Motor. The Ultra Cool Reefer Oil cooler has been installed for a few years. The oil temp on the highway is about 180 and in the city stop and go it is about 220. A digital gauge Dakota sensor unit is mounted in the tank and the gauge is on the handlebar next to the light that indicates the fans are running on the cooler. This is Central FL. There have been no issues what so ever until now with the thermal sensor failure. A new on is on the way. Am satisfied with this product and the reusable cleanable oil filter as well.
