The recommended tire pressure for the Yamaha XC155H SMAX 2017 is 29 psi for the front tire and 33 psi for the rear tire.
It is recommended to change the engine oil every 3,000 miles or every 6 months, whichever comes first, to ensure optimal performance and longevity.

To adjust the idle speed, locate the idle adjustment screw on the carburetor. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, aiming for an idle speed of around 1,500 RPM.
Common causes of starting problems include a weak or dead battery, faulty spark plug, clogged fuel system, or issues with the starter motor. Be sure to check these areas if you experience starting issues.
To improve fuel efficiency, ensure regular maintenance such as timely oil changes, keeping tires properly inflated, using high-quality fuel, and avoiding excessive idling and rapid acceleration.
If your scooter overheats, stop and turn off the engine immediately. Allow it to cool down, check the coolant level, and inspect for any leaks or blockages in the cooling system. If the issue persists, consult a Yamaha service center.
To replace the brake pads, remove the caliper bolts, slide out the caliper, remove the old pads, and insert the new ones. Ensure that the pads are properly seated and reassemble the caliper before testing the brakes for proper function.
To winterize your scooter, clean it thoroughly, change the oil, add fuel stabilizer, remove the battery and store it in a warm place, and cover the scooter to protect it from dust and moisture.
Symptoms of a worn-out drive belt include a noticeable decrease in acceleration, unusual noises coming from the belt area, and visible wear or cracks on the belt. It is recommended to inspect and replace the drive belt every 12,000 miles.
