To adjust the rear suspension, locate the preload adjuster on the shock absorber. Use a spanner to turn the adjuster clockwise to increase preload (stiffer ride) or counterclockwise to decrease preload (softer ride). Ensure both sides are adjusted equally for balanced handling.
The recommended engine oil for the Hero Karizma ZMR 2018 is 10W-30, API SL grade or higher, 4-stroke motorcycle engine oil. Ensure regular oil changes every 3,000 to 4,000 kilometers for optimal performance.
If you're experiencing starting issues, check the battery connections for corrosion or looseness, ensure the fuel valve is open, examine the spark plug for wear or fouling, and verify that the kill switch is set to 'Run'. If problems persist, consult a professional mechanic.
The recommended tire pressure for the Hero Karizma ZMR 2018 is 25 psi for the front tire and 28 psi for the rear tire. Proper tire pressure ensures better handling and fuel efficiency.
Regular maintenance checks should be performed every 6 months or 3,000 kilometers, whichever comes first. Key areas to inspect include the engine oil, brakes, chain tension, tire condition, and electrical systems.
If the engine overheats, stop the motorcycle immediately and turn off the engine. Allow it to cool, check the coolant level, and inspect for any leaks. Avoid riding until the issue is resolved. If necessary, seek assistance from a qualified mechanic.
To clean the air filter, remove the housing cover, take out the air filter, and gently wash it with a mild detergent. Allow it to dry completely before reinstalling. Replace the filter if it shows signs of excessive wear or damage.
Common electrical issues include blown fuses, faulty wiring, and weak battery connections. Check and replace any blown fuses, inspect wiring for damage or corrosion, and ensure battery terminals are tight and clean. If electrical problems persist, consult a professional.
To adjust the chain tension, place the motorcycle on its main stand, loosen the rear axle nut, adjust the chain tensioners on both sides evenly, and ensure there is 20-30mm of slack in the chain. Tighten the axle nut securely after adjustment.
Key maintenance tips include regular oil changes, keeping the chain lubricated, maintaining proper tire pressure, checking brake pads for wear, and ensuring all electrical components function properly. Regular servicing by a qualified mechanic is also recommended.
