  Trevor CrawfordAug 13, 2025
  If your Polaris Offroad Vehicle engine turns over but fails to start, there are several possible causes. First, ensure you have fuel. If out of fuel, refuel, cycle the key to the ON position three times for 5 seconds each, then try to start it. Check for a clogged fuel filter and replace it if necessary. Also, check for water, old, or non-recommended fuel and replace it with fresh, recommended fuel. Inspect the spark plugs for fouling or defects and replace them if needed. Low battery voltage can also be a factor, so recharge the battery to 12.8 VDC.

  If your Polaris Offroad Vehicle engine stops or loses power, several factors could be responsible. Begin by checking if you're out of fuel. If so, refuel, cycle the key to the ON position three times for 5 seconds each, and then start. Inspect the fuel vent line for kinks or plugs and replace it if necessary. Also, check for water in the fuel and replace it with new fuel. Inspect, clean, and/or replace any fouled or defective spark plugs. Ensure that you recharge the battery to 12.8 VDC if the voltage is low.

Check for loose ignition connections and tighten them. Replace the fuel if water is present. Recharge the battery to 12.8 VDC if the voltage is low. Inspect the air filter and clean or replace it if clogged. Replace the fuel filter if it is clogged.

How to prevent drive belt wear on my Polaris Sportsman 570 EFI Offroad Vehicle?
- K
  Kathleen WintersAug 28, 2025
  Drive belt wear or burn in your Polaris Offroad Vehicle can occur due to several reasons. To prevent this, always warm up the belt by operating below 30 MPH for one mile (5 miles or more when the temperature is below freezing). If you are stuck in mud or snow, shift the transmission to low range and carefully use fast, aggressive throttle application to engage the clutch. Be cautious, as excessive throttle may cause loss of control and vehicle rollover. When driving onto a pickup or tall trailer, use low range during loading. If belt slippage occurs due to water or snow ingestion into the PVT system, dry out the PVT. Inspect clutch seals for damage if repeated leaking occurs.

  James NguyenAug 31, 2025
  If your Polaris Offroad Vehicle engine backfires, several factors could be the cause. Inspect, clean, and/or replace the spark plugs if the spark is weak. Set the gap to specifications or replace the plugs if the spark plug gap or heat range is incorrect. Replace the fuel with fresh, recommended fuel if the current fuel is old or non-recommended. Check all ignition connections and tighten them if loose. Also, replace with fresh recommended fuel if water is present in fuel.
