On my 110-mile test ride I traveled on the freeway, gravel roads, and paved, secondary roads. My engine oil temperatures were usually running 170-210 degrees, Fahrenheit. I rode at 75-80 mph for 26 miles on the interstate. At the end of that ride my engine oil reached a high temperature of 258 degrees. I backed off the throttle to 65 mph for the last 3 miles before my exit, and the oil temperature dropped to 250 degrees before I exited the freeway. Once off the freeway, the oil temperatures quickly returned to lower levels. If you turn off the engine, the oil temperature cools rapidly. If necessary, I plan to cut out the drilled portion of my front fender, and install aluminum hardware mesh to increase airflow to the oil cooler. However, I will wait for warmer weather to see if this is necessary.
