Howdy. I've added an XR400-type oil cooler to my XR300 (formerly an XR250). Understandably, my OEM XR250 shop manual doesn't list a torque spec for the (flange?) nuts that connect the oil llines to the oil cooler. Could one of you XR400 types with a manual please tell me the torque spec (assuming your XR400 OEM manual lists such a spec). Thanks. Dale And thanks for the !!!
