    ATV Repair and Maintenance
    I have a 96 polaris 400 sport 2 stroke that I just got and replaced water pump and oil pump seals and bearing. Drove it for a couple of hours, parked it. Started right up next day easy as pie and rode an hour and it ran strong and then it started loosing power so I shut it down right away...
