To check the engine oil level, ensure the bike is on level ground. Start the engine and let it warm up for a few minutes, then turn it off. Wait for a few minutes to allow the oil to settle. Remove the oil filler cap/dipstick, wipe it clean, reinsert without screwing it in, and then remove it again to check the level. The oil should be between the "L" (low) and "F" (full) marks.
The recommended tire pressure for the Suzuki Boulevard C90B VL1500B is typically 36 psi for the front tire and 40 psi for the rear tire. Always refer to the owner's manual or the tire information on the motorcycle for exact specifications.
If your motorcycle won't start, check the battery connections for tightness and corrosion. Ensure the kill switch is in the 'Run' position. Check the fuel level and make sure the fuel valve is open. Inspect the spark plugs for wear or fouling and replace if necessary. If the issue persists, it may require professional diagnostic.
It is recommended to inspect the air filter every 3,000 miles and replace it every 12,000 miles or as needed based on riding conditions. Riding in dusty environments may require more frequent changes.
Use a high-quality ethylene glycol-based antifreeze specifically designed for aluminum engines. It should be mixed with distilled water in a 50:50 ratio. Always check the owner’s manual for specific recommendations.
The rear suspension can be adjusted for preload using the adjuster located on the shock absorber. Use a suitable spanner to turn the adjuster ring to increase or decrease preload. Refer to the owner's manual for detailed instructions and recommended settings based on rider weight and load.
Spongy brakes may indicate air in the brake lines or worn brake pads. Check the brake fluid level and top up if necessary. Bleed the brakes to remove any air bubbles. Inspect the brake pads for wear and replace them if they are below the minimum thickness.
To maintain the battery, ensure it is fully charged especially during periods of inactivity. Clean the terminals and apply a light coat of dielectric grease to prevent corrosion. Use a battery tender to keep it charged if the motorcycle is not used frequently.
To change the spark plugs, remove the seat and fuel tank for easier access. Disconnect the spark plug leads and use a spark plug socket to remove the old plugs. Install new spark plugs, ensuring they are gapped correctly, and tighten them to the specified torque. Reconnect the leads and reassemble the motorcycle.
To adjust the clutch lever, locate the adjuster near the lever pivot. Turn the adjuster to achieve the desired free play, typically 10-15mm at the lever's end. Ensure the clutch engages smoothly without slipping or dragging.
