For Polaris Youth models like the Predator 50, 90, and Sportsman 90, it is recommended to use Polaris 2-Stroke Oil for optimal performance and protection.
Tire pressure should be checked before each ride. Ensure that the pressure is within the manufacturer's specifications, typically found in the owner's manual.
To store your Polaris Youth ATV during the winter, clean it thoroughly, disconnect the battery, add a fuel stabilizer, and cover it to protect from dust and moisture.
Check the battery for charge, ensure the fuel is fresh, inspect the spark plug for wear or damage, and verify that the kill switch is not engaged.
Regular maintenance includes checking and replacing the oil, inspecting the brakes, cleaning the air filter, and tightening any loose bolts or screws.
To adjust the chain tension, loosen the rear axle nuts, adjust the tensioner bolts until the chain has about 1/2 inch of slack, then retighten the axle nuts.
If your ATV is overheating, check the coolant level, ensure the radiator is not clogged, and verify that the cooling fan is operational.
The air filter should be checked after every 10 hours of use and replaced if it shows signs of excessive dirt or damage.
During the break-in period, avoid full-throttle operation, vary engine speed, and avoid prolonged operation at constant speed to ensure proper engine seating.
Remove the carburetor, disassemble it carefully, clean all passages and components with carburetor cleaner, and reassemble it following the service manual instructions.
