Quad bike safety in 2025

Why Your Quad/ATV Won’t Start

Fuel Issues

  • Check Delivery: Clogged fuel filter or faulty pump? Ensure fuel reaches the engine.
  • Fuel Quality: Use fresh, non-ethanol fuel—old or contaminated fuel can clog the system.

Ignition Problems

  • Spark Plug: Inspect for damage or fouling—replace if worn.
  • Ignition Coil/CDI: Test these components; a faulty coil or CDI can prevent sparking.

Mechanical and Electrical Checks

  • Engine: Seized engine or damaged piston rings can stop it from starting.
  • Battery/Wiring: Ensure the battery is charged and connections are clean.
  • Switches/Sensors: Check the kill switch, neutral safety switch, and throttle sensor.
  • Exhaust: Clear any blockages like mud or debris.
  • Choke: For carbureted quads, ensure the choke works—key in cold weather.
  • Starter Motor/Relay: Listen for clicks; replace if faulty.

When to Call a Pro

If these steps don’t work—think complex electrical issues or engine damage—it’s time for a mechanic.

Prevent Future Issues

  • Clean Regularly: Wash off mud after rides to avoid clogs.
  • Seasonal Care: Use fuel stabiliser and disconnect the battery for storage.
  • Inspect Often: Check for worn wires, spark plugs, and seals.
  • Listen Up: Odd noises or behaviors can signal early problems.

Keep your quad/ATV running smoothly with these tips!
