X 1120 D Overheated

This past Sunday, I was riding to check my trail cameras, and my overheat alarm sounded. I immediately killed engine, turned key to on position, and fan ran as it should. I let machine sit with fan running while I inspected all hoses, and fluid levels. I could not locate an issue other than water reservoir was just a hair above low line (and im guessing that was only because of overheating and evaporation). It took approximately 10 minutes for engine to cool to normal operating temps (between 2 and 3 bars on digital screen). I was able to ride it out of woods and down county road 3 miles back to camp at full throttle without anymore overheating. I loaded up machine and took it home, where I again checked all fluid levels, topped off reservoir with water (only held about 8 oz), cleaned radiator and screen. I then rode machine in low at wide open throttle, for approximately half an hour, and operating temps held at 2 bars (normal operating temp). I'm pretty stumped as to what caused this, unless the thermostat just simply stuck for a brief period of time. I only have 80 hours on machine and have had no other issues. Anyone else with similar experiences, or suggestions as to what caused this?
 
I don't have the same RTV as you but did you check the radiator for blockage?
Did a plastic bag or something get pulled in and cover the radiator in whole or part then when you stopped, it fell off the fins?
 
I did drive through some fields with tall seedy johnson and bahia grass. It did not appear to be dirty enough to cause blockage.
 
I had the exact same thing happen with my RTV X 1100 yesterday. The strange thing was I had cleaned everything the evening before at it was running great. I was driving up a steep hill when the red light and alarm came on, had only gone about a mile. I thought perhaps a belt broke but everything was fine. Let it sit for about 10 minutes while I double checked everything, then turned it back on and it ran great. I've got about 70 hours on mine.
 
I had this happen once in a foreign car i once owned and it turned out to be the cooling system had air in it. in that particular instance it was a very difficult thing to bleed properly.i noticed bleed on my x1100 behind the cab on the drivers side in a very high location and have always thought that bleeding the cooling system on the RTV must be critical. i think there are several more bleed areas on that system also. that is where i would start.
