Hero Passion Pro 2014 Owner's Manual

To adjust the chain tension, place the motorcycle on the center stand. Loosen the axle nut and adjust the chain tensioners on both sides evenly until the chain has about 20-30mm of slack. Tighten the axle nut securely and recheck the tension.
The recommended engine oil for Hero Passion Pro 2014 is 10W-30 grade oil. Ensure it meets the API SL or JASO MA2 standards for optimal performance.
To improve fuel efficiency, maintain proper tire pressure, follow regular maintenance schedules, use recommended engine oil, avoid excessive idling, and ride at a consistent speed without rapid acceleration.
If the bike won't start, check the fuel level, ensure the kill switch is off, inspect the spark plug for wear or damage, check the battery charge, and ensure the fuel valve is in the correct position.
It is recommended to service your Hero Passion Pro every 3,000 to 4,000 kilometers or every 6 months, whichever comes first. Regular service includes oil change, air filter cleaning, and checking brakes and chain tension.
To check the brake fluid level, locate the brake fluid reservoir on the handlebar. Ensure the bike is on a level surface and the handlebars are straight. The brake fluid should be between the minimum and maximum marks on the reservoir.
Common electrical issues include blown fuses, faulty wiring connections, and battery discharge. Regularly inspect connections for corrosion, ensure the battery is charged, and replace fuses as needed.
To clean the air filter, remove the seat and locate the air filter box. Open the box, take out the filter, and clean it using compressed air. If the filter is too dirty or damaged, replace it with a new one.
Maintain a tire pressure of 25 psi for the front tire and 30 psi for the rear tire for optimal performance and safety. Check the tire pressure regularly and adjust as necessary.
To troubleshoot a misfiring engine, check the spark plug for wear or damage, ensure the fuel is clean and the fuel line is unobstructed, and check for any air leaks in the intake manifold.
