Yamaha VMX17J, VMX17JC VMAX 2018 Owner's Manual

To improve fuel efficiency, ensure regular maintenance such as timely oil changes, maintaining correct tire pressure, and using high-quality fuel. Avoid aggressive acceleration and maintain a steady speed whenever possible.
Check the battery connections to ensure they are tight and corrosion-free. Inspect the fuses and replace any that are blown. If the problem persists, consider checking the starter motor or consult a professional technician.
Change the oil every 4,000 miles or at least once a year, whichever comes first. Use the recommended oil type as specified in the owner's manual for optimal performance.
The recommended tire pressure is 36 psi for the front tire and 42 psi for the rear tire. Always check the tire pressure when the tires are cold for an accurate reading.
Start by checking the battery charge and connections. Inspect all wiring for signs of wear or damage. Use a multimeter to check for continuity and voltage. If necessary, consult the wiring diagram in the service manual.
Use a high-quality ethylene glycol-based coolant mixed with distilled water at a 50/50 ratio. Ensure the coolant is compatible with aluminum engines to prevent corrosion.
Regularly check the brake fluid level and top up if necessary using the recommended DOT 4 brake fluid. Inspect brake pads for wear and replace them if they are below the minimum thickness. Ensure the brake lines are free from leaks or damage.
If the engine overheats, pull over safely and turn off the engine. Allow it to cool down before checking the coolant level. Refill if low, and inspect for leaks or blockages in the cooling system. If the problem persists, have the system checked by a professional.
To adjust the suspension, refer to the owner's manual for guidance on adjusting the front forks and rear shock absorber settings. Adjust preload, compression, and rebound damping to suit your riding style and load.
Common causes of engine misfire include faulty spark plugs, a clogged air filter, or a malfunctioning fuel injector. Inspect and replace any defective components and ensure regular maintenance to prevent misfires.
