This is a 2022 Polaris 450 with about 2.5 hours on it. I am towing a trail mower. The transmission is in low and the top speed is about 7 mph. The ground is level and the temperature is about 55 degrees. I am mowing the back yard and the ATV temperature runs between 195 and 210 most of the time. But every 20 minutes or so it runs up to 235. I let it sit idling and it drops right back to 205. Any idea what is wrong with this? Thanks! Philip - [email protected]. 503-319-9181
