To change the oil, warm up the engine, place the bike on a level surface, and remove the oil drain plug. Allow the oil to completely drain, then replace the plug. Remove the oil filter and install a new one. Finally, refill with the recommended oil type and check the level.
The Suzuki Boulevard S40 LS650B 2018 is designed to run on regular unleaded gasoline with a minimum octane rating of 87.
Check the battery charge and connections, ensure the kill switch is in the 'run' position, check the fuel level, and inspect the spark plug for wear. If issues persist, consult a professional.
The recommended tire pressure is 29 psi for the front tire and 36 psi for the rear tire. Always check the pressure when the tires are cold.
Regularly clean the chain with a suitable cleaner, lubricate it with motorcycle chain lube, and adjust the tension according to the owner's manual specifications.
Stop the motorcycle in a safe location, turn off the engine, and allow it to cool. Check the coolant level if applicable and ensure proper airflow to the radiator. Avoid running the engine under heavy loads in high ambient temperatures.
The air filter should be inspected every 4,000 miles and replaced if necessary. However, it may require more frequent changes if riding in dusty conditions.
To winterize, clean the motorcycle thoroughly, change the oil, add fuel stabilizer, disconnect the battery, and store the bike in a dry place. Cover it to protect from dust and moisture.
Locate the adjuster near the clutch lever, loosen the lock nut, and turn the adjuster screw to achieve the desired lever play, usually about 10-15mm. Tighten the lock nut afterwards.
Maintain proper tire pressure, use the recommended fuel grade, keep the motorcycle well-maintained, reduce excessive idling, and ride smoothly at consistent speeds to improve fuel efficiency.
