my atv has been over heating for some time now, the last time i took it out it was good for about 1.5 hours then she went into limp mode.. when i got home i changed the glycol to engine ice. i also noticed now that my rocker covers are leaking oil.. on the clutch side in the back. hopefully i just have to replace the gasket. it has about 3000 miles. just wondering on some ideas about the over heating problem just incase it happens again.
