I have 2021 ultra limited with a 131 in it. The bike oil temp would run between 250 and 280 degrees on a 90 to 100 degree day doing 70to 75 mph. Took a trip to the black hills my engine oil temp went to 310 degrees on 85 to 95 degree day pulling the hills curves.. after I put the ultra cool and flo oil filter on my Temps have dropped 50 to 60 degrees. The only time the fans turn on is when I’m in stop and go traffic. I’ve also noticed the water cooling fans don’t run as much.. I would definitely recommend putting a ultra cool oil cooler on your bike. It’s also made a big difference in heat coming off of engine.
