Before each ride, check the engine oil level. Refer to the engine's dipstick or sight glass for proper levels. Use recommended 4-stroke engine oil (e.g., SAE 10W-30 or 10W-40). Add oil if necessary, but do not overfill.

4.6 Tire Pressure

Check tire pressure before each ride. Refer to the tire sidewall for recommended PSI. Proper tire pressure is crucial for safety and handling.
