Regularly clean and lubricate the chain every 500 miles or after riding in wet conditions. Use a motorcycle-specific chain cleaner and lubricant. Check for proper tension, which should have about 1 inch of slack.
It is recommended to change the engine oil every 4,000 miles or at least once a year. Use SAE 10W-30 motorcycle oil for optimal performance.
Check the battery connections for corrosion and ensure they're tight. Verify the kill switch is in the 'Run' position, and make sure the fuel valve is turned on. If the problem persists, check the spark plugs and fuel system.
Ensure the coolant level is adequate and check for any leaks. Inspect the radiator for clogs or debris. Make sure the fan is operational. If the issue continues, consult a professional mechanic to check the thermostat and water pump.
Brake pads should be inspected every 4,000 miles and replaced when the pad material is worn down to 2mm thickness. Riding style and conditions can affect wear, so check them regularly.
For optimal performance, maintain the front tire at 29 psi and the rear tire at 33 psi. Always check tire pressure when the tires are cold.
To adjust the clutch lever, locate the adjuster at the lever perch, loosen the locknut, and turn the adjuster to achieve 10-20mm of free play. Tighten the locknut after adjusting.
Fill the fuel tank and add a fuel stabilizer. Change the oil and filter, lubricate moving parts, and disconnect the battery. Store the motorcycle in a dry place and cover it to protect from dust and moisture.
Remove the spark plug cap, unscrew the spark plug using a spark plug wrench, and inspect for wear or deposits. The electrode should be clean and the gap should be set to 0.8-0.9mm. Replace if necessary.
Remove the air filter cover and take out the filter. If it's a foam filter, wash it with mild soapy water and let it dry completely. Lightly oil the filter before reinstalling. For a paper filter, replace it if it appears dirty.
