The recommended oil for the Yamaha YP400B Majesty 2012 is SAE 10W-40, API Service SG type or higher.
It is recommended to change the oil every 3,000 miles or every 6 months, whichever comes first.
The recommended tire pressure for the front tire is 29 psi and for the rear tire is 33 psi.
Check the battery charge, starter motor, and ignition system. Ensure that the fuel system is supplying fuel and that there are no blockages.
Inspect the drive belt for wear and tear every 12,000 miles and replace it if necessary. Avoid excessive acceleration to extend its lifespan.
Use a high-quality ethylene glycol-based antifreeze coolant mixed with distilled water in a 1:1 ratio.
Remove the air filter cover, take out the air filter element, and clean it with compressed air or replace it if it's too dirty or damaged.
Maintain proper tire pressure, perform regular maintenance, avoid rapid acceleration, and ensure the engine is tuned correctly.
Check the brake fluid level and look for any signs of air in the brake lines. Bleed the brakes if necessary and inspect the brake pads for wear.
Locate the headlight adjustment screws, usually found near the headlight assembly, and adjust them to align the headlight beam to the desired height and angle.
