To perform an oil change, warm up the engine, place the scooter on its center stand, remove the oil filler cap, and drain the oil by removing the drain bolt. Replace the oil filter if necessary, reinstall the drain bolt, and refill with the recommended oil type and quantity.
The recommended tire pressure for the Yamaha XC155G SMAX 2016 is 29 psi for the front tire and 33 psi for the rear tire. Always check the tire pressure when the tires are cold.
Starting issues can be caused by a weak battery, faulty spark plug, or fuel delivery problems. Check the battery voltage, inspect and clean the spark plug, and ensure the fuel lines are clear and the fuel pump is functioning properly.
At 5,000 miles, perform an oil change, inspect the air filter, check the brake fluid level, inspect the drive belt for wear, and ensure all lights and signals are functioning properly.
To adjust the headlight beam, locate the adjustment screws on the back of the headlight assembly. Turn the screws clockwise to lower the beam and counterclockwise to raise it. Ensure the scooter is on level ground when making adjustments.
The recommended coolant for the Yamaha XC155G SMAX 2016 is a 50/50 mixture of ethylene glycol-based antifreeze and distilled water. Ensure it is suitable for aluminum engines and provides freeze and corrosion protection.
To improve fuel efficiency, ensure regular maintenance is performed, keep tires inflated to the recommended pressure, avoid aggressive acceleration, and reduce excess weight carried on the scooter.
If the engine overheats, safely pull over and turn off the engine. Allow it to cool before checking the coolant level and the radiator for any blockages. Refill coolant if necessary and inspect for leaks or faulty components.
To replace brake pads, elevate the scooter, remove the caliper bolts, and slide the caliper off the disc. Remove the old pads, compress the caliper piston, and install new pads. Reattach the caliper and ensure proper alignment and torque.
To check and adjust valve clearance, remove the necessary body panels and access the engine head. Rotate the engine to the top dead center of the compression stroke, and use a feeler gauge to measure the clearance. Adjust using the tappet adjuster if needed.
