Sooo... I may have made an error about the max temp my 99 XT reached at 65mph. I did the seat of pants research about 8 years ago and I was thinking the small Harbor Freight thermometer had a max temp rating of 250 deg F. What I noted was it went over range after about 5 minutes running at 65. At 55 MPH it stayed around 200-225 deg F. I lost the paperwork for the thermometer I used, but while looking for a newer one with a higher range to see if it did stabilize at a higher temp I found the current model that looks exactly like the one I used has a max temp range of 230 deg F. They have a new model that is small which goes to over 400 deg F that seems a better tool than what I used. It would be nice to make a graph of engine temp vs speed at different ambient temps. I'm not the one to invest in the instrumentation for it though.... Didn't want to possibly lead anybody astray.
