all right here is my story... i have a 2000 rmk 700.. running great.. went on a sled trip on tue sled was running great up till 4 hrs into the ride ... then it just died? the key was on and kill switch up.. soo i let it cool down. for 10 min or so.. it starts back up and goes 1/4 mile and it starts to backfire really bad and shuts off.... so i get towed out 13 miles. get it home. and let the thing thaw out once it was dried out i pulled the rope it runs just fine... i took the water pump cover of to see if the water pump belt was broken. but is was not and the water pump looks to be in good shape.. but can a water pump go out looking sooo good...???? or is it something else? stator? oil? why overheat problems??? and why the back fire???? oil pump? i do not know please help me narrow this down..
