so tonight i went for a ride on my 07 f1000, not to long into it my coolant light was flashing, so i pulled over and stopped, and went on my way on the groomed sled trail. it came on again, and then off and then on again. until finally it just flashed while i was riding. mind you im riding on snow couvered trails. it would stop for a duartion of time, but then come back on again. this didint happen the last few rides of been on on the same trail but it did tonight. any idea as to why?? if the light flashes is it low coolant?, at one point it went solid on so i turned off immeditatly, i just cannot beileve that at -20 c and on a groomed trail this sled will over heat. any ideas or had anyone had the same problem????
