What to do if my Polaris Offroad Vehicle engine turns over but fails to start?
- K
  Kristina LarsonAug 18, 2025
  If your Polaris Offroad Vehicle's engine turns over but doesn't start, the issue could stem from several causes. First, ensure there is fuel in the tank. Other potential problems include dirt in the fuel line or filter, a fuel valve that won't allow fuel to pass, an inoperative or restricted fuel pump, or a plugged or pinched tank vent. Additionally, the engine might be flooded, have low compression due to high cylinder leakage, or have a fouled spark plug or faulty ignition components.

Why is my Polaris Sportsman 700 Efi 2005 overheating?
- M
  Mary MartinezAug 23, 2025
  Your Polaris Offroad Vehicle might be overheating due to several reasons: low coolant level, air in the cooling system, using the wrong type or mix of coolant, a faulty pressure cap or system leaks, or a restricted system caused by mud or debris. Other potential causes include a lean mixture, weak fuel pump output, electrical malfunction, water pump failure, thermistor failure, an inoperative or slow cooling fan, misadjusted ignition timing, low oil level, incorrect spark plug heat range, a faulty hot light circuit, or a thermostat stuck closed.

What causes spark plug fouling in my Polaris Sportsman 700 Efi 2005 Offroad Vehicle?
- C
  Christopher HarmonAug 26, 2025
  Spark plug fouling in your Polaris Offroad Vehicle can occur due to several reasons. These include a loose or faulty spark plug cap, incorrect spark plug heat range or gap, an incorrectly calibrated or worn PVT system, poor fuel quality or octane level that is too high, low compression, a restricted exhaust, or weak ignition. Other possible causes are a mis-adjusted ETC switch, a restricted air filter or breather system, an improperly assembled air intake system, a restricted engine breather system, or oil contaminated with fuel. To resolve this, check or replace the spark plug cap. You can also adjust spark plug heat range or gap.

What to do if Polaris Sportsman 700 Efi 2005 has low compression?
- A
  Anthony HessAug 28, 2025
  Low compression in your Polaris Offroad Vehicle can be attributed to a cylinder head gasket leak, no valve clearance (cam wear), a worn cylinder or piston, worn, leaking, broken, or sticking piston rings, a bent or stuck valve, a broken or weak valve spring, a valve not seating properly, or a sticking rocker arm. To address this, replace the cylinder head gasket. You can also adjust valve clearance.

Why does my Polaris Offroad Vehicle engine run but will not idle?
- C
  Christopher TurnerAug 30, 2025
  If your Polaris Offroad Vehicle engine runs but won't idle, it could be due to a restricted carburetor pilot system. Other potential causes are low compression or a restricted crankcase breather. To fix this, clean the carburetor pilot system, or clear restrictions in crankcase breather.

What causes backfiring in my Polaris Offroad Vehicle?
- J
  Julie DavisSep 1, 2025
  Backfiring in your Polaris Offroad Vehicle can be caused by an ETC or speed limiter system malfunction, a fouled spark plug or incorrect plug or plug gap, exhaust system air leaks, or a faulty ignition system. Other potential causes include poor connections in the ignition system, a sticking valve, air leaks in the intake, or a lean condition. To address this, inspect and repair the ETC or speed limiter. Also, replace the spark plug with the correct type and gap.

Why does my Polaris Offroad Vehicle engine idle but will not rev up?
- D
  David GonzalezSep 4, 2025
  If your Polaris Offroad Vehicle engine idles but won't rev up, it could be due to a fouled spark plug or weak spark. Other potential causes include a broken throttle cable, an obstruction in the air intake, a removed air box, incorrect or restricted carburetor jetting, the ETC switch limiting speed, the reverse speed limiter limiting speed, incorrect ignition timing, a restricted exhaust system, or an excessively worn cam. To resolve this, replace the fouled spark plug.

Why does my Polaris Offroad Vehicle engine have low power?
- S
  Stacy CrosbySep 6, 2025
  Your Polaris Offroad Vehicle engine might have low power due to a fouled spark plug. Other possible causes include cylinder, piston, ring, or valve wear or damage, a PVT not operating properly, a restricted exhaust muffler, or an excessively worn cam. To fix this, replace the fouled spark plug.

What causes excessive smoke and carbon buildup in my Polaris Sportsman 700 Efi 2005?
- J
  Joshua MillerSep 8, 2025
  Excessive smoke and carbon buildup in your Polaris Offroad Vehicle can be caused by excessive piston-to-cylinder clearance, wet sumping, worn rings, piston, or cylinder, worn valve guides or seals, a restricted breather, or a dirty or contaminated air filter. To address this, check and repair piston-to-cylinder clearance.
