I've got a dipstick temp gauge on my XR650L. On my last ride, I saw the temp go higher than it ever has - 260 deg. Based on the oil level after the ride, it did seem to burn some. I found some info on other forums saying that after a high temp ride, you should change the oil. I'm running Mobil 1 4t 10-40 synthetic and have about 700 miles on it. Should I change the oil after running at 260 deg to be safe or is it not even a concern? Thanks.
