The recommended oil type for the Honda TRX90X Sportrax 90X 2020 ATV is SAE 10W-30, JASO T 903 MA standard.
It is recommended to change the oil every 100 hours of operation or annually, whichever comes first.
The correct tire pressure for the front tires is 2.5 psi and for the rear tires is 2.9 psi.
To adjust the chain tension, loosen the rear axle nuts and adjust the chain adjusters equally on both sides until the chain has the proper slack. Then retighten the axle nuts securely.
Remove the air filter, wash it in soapy water, rinse thoroughly, allow it to dry completely, and then apply air filter oil before reinstalling.
First, check the battery charge and connections, ensure the fuel valve is on, inspect the spark plug for wear or damage, and verify that the kill switch is in the run position.
Regularly inspect the brake pads for wear, check the brake fluid level, and ensure the brake cables are properly adjusted and free of damage.
Clean the ATV thoroughly, change the oil, fill the fuel tank and add a fuel stabilizer, disconnect the battery, and store it in a dry, covered location.
Check the coolant level and top off if necessary, ensure the radiator is not obstructed by debris, and make sure the cooling fan is operational.
Remove the spark plug cap, use a spark plug wrench to unscrew the old plug, then install a new spark plug (properly gapped) and reattach the spark plug cap.
