The recommended engine oil for the Honda Monkey 125 2019 is SAE 10W-30, API service classification SG or higher.
It is recommended to change the engine oil every 4,000 miles (6,400 kilometers) or every year, whichever comes first.
To adjust the chain tension, place the bike on its side stand, loosen the axle nut, adjust the chain tensioner bolts, and ensure the slack is within specifications (20-30 mm). Tighten the axle nut after adjustment.
Check the battery connections, ensure the fuel valve is open, inspect the spark plug for fouling, and verify that the engine cut-off switch is in the 'run' position. If the issue persists, further diagnosis may be required.
Regularly check the brake fluid level and brake pad wear. Replace the brake pads if the wear indicator is visible, and bleed the brake system if the brake feels spongy.
The recommended tire pressure for the Honda Monkey 125 2019 is 29 psi (200 kPa) for the front tire and 33 psi (225 kPa) for the rear tire.
Clean the motorcycle thoroughly, fill the fuel tank and add a fuel stabilizer, change the oil, charge the battery, and cover the motorcycle to protect it from dust and moisture. Store it in a dry, cool place.
Remove the air filter cover, take out the air filter, and gently clean it using compressed air or replace it if it is excessively dirty or damaged. Ensure it is dry before reinstalling.
To improve fuel efficiency, maintain proper tire pressure, perform regular engine maintenance, avoid aggressive acceleration, and reduce idling time.
Regular maintenance should include checking and changing engine oil, inspecting and adjusting the chain, checking brake fluid and pads, inspecting tires and pressure, and cleaning the air filter.
