The Arctic Cat XR 700, once a strong contender in the ATV market, has unfortunately been plagued with its share of issues. While known for its powerful engine and comfortable ride, potential buyers and current owners need to be aware of the common problems that can arise. Addressing these issues proactively can save you time, money, and frustration down the trail. Let's dive into some of the most frequently reported problems with the Arctic Cat XR 700.

Engine Troubles: When the Roar Turns into a Whimper

One of the most concerning areas for XR 700 owners revolves around engine performance and reliability. While the 700cc engine is generally robust, several recurring issues can hinder its performance.

Valve Train Issues: A common complaint centers around the valve train. Problems often manifest as excessive valve noise, difficulty starting, or a noticeable loss of power. This can stem from several factors:

  • Worn Valve Seats: Over time, the valve seats can wear down, leading to improper valve sealing. This reduces compression and negatively impacts engine performance.
  • Stretched Timing Chain: The timing chain synchronizes the crankshaft and camshaft. If it stretches, it can throw off the engine's timing, causing misfires, reduced power, and even engine damage.
  • Incorrect Valve Lash: Proper valve lash (the clearance between the valve stem and rocker arm) is crucial. If it's too tight or too loose, it can lead to valve damage and performance problems.

What to do: Regular valve adjustments are crucial. Consult your owner's manual for the recommended intervals. If you hear excessive valve noise, don't ignore it. Have a qualified mechanic inspect the valve train to identify and address any issues before they escalate. Consider upgrading to a higher-quality timing chain for increased durability.

Fuel Delivery Problems: A smooth-running engine relies on a consistent fuel supply. Fuel delivery issues can cause a range of problems:

  • Clogged Fuel Filter: A dirty fuel filter restricts fuel flow, leading to poor performance, stalling, and difficulty starting.
  • Faulty Fuel Pump: The fuel pump delivers fuel from the tank to the engine. If it fails or becomes weak, it can cause fuel starvation, especially under heavy load.
  • Dirty Fuel Injector: The fuel injector sprays fuel into the engine. If it becomes clogged, it can disrupt the fuel mixture, leading to poor performance and increased emissions.

What to do: Regularly replace the fuel filter according to the manufacturer's recommendations. Consider using a fuel stabilizer to prevent fuel degradation and keep the fuel system clean. If you suspect a fuel pump issue, have it tested by a qualified mechanic. Fuel injector cleaner might help with minor clogs, but severely clogged injectors may need professional cleaning or replacement.

Overheating: The Arctic Cat XR 700, like any high-performance engine, can be susceptible to overheating if the cooling system isn't functioning properly.

  • Clogged Radiator: Dirt, mud, and debris can accumulate in the radiator fins, reducing its ability to dissipate heat.
  • Low Coolant Level: Insufficient coolant reduces the cooling system's efficiency.
  • Faulty Thermostat: The thermostat regulates coolant flow. If it fails to open properly, it can restrict coolant flow and cause overheating.
  • Defective Fan: The cooling fan helps dissipate heat when the ATV is stationary or moving slowly. If the fan fails, it can lead to overheating, especially in hot weather.

What to do: Regularly clean the radiator fins with a soft brush and water. Check the coolant level regularly and top it off as needed. Inspect the thermostat and cooling fan for proper operation. If you suspect a problem, have them tested and replaced if necessary. Consider using a coolant additive to improve heat transfer.

Transmission Troubles: Shifting Gears and Avoiding Tears

The transmission is another area where XR 700 owners have reported issues. Smooth shifting and reliable operation are essential for a positive riding experience.

Hard Shifting: Difficulty shifting gears is a common complaint. This can be caused by several factors:

  • Worn Clutch: A worn clutch can cause slipping and make it difficult to engage gears smoothly.
  • Stiff Shift Linkage: The shift linkage connects the shift lever to the transmission. If it becomes stiff or binding, it can make shifting difficult.
  • Low Transmission Fluid: Insufficient transmission fluid can lead to increased friction and difficulty shifting.

What to do: Inspect the clutch for wear and replace it if necessary. Lubricate the shift linkage with a quality lubricant. Check the transmission fluid level and top it off as needed. If the problem persists, consult a qualified mechanic.

Belt Problems: The CVT (Continuously Variable Transmission) system relies on a belt to transfer power from the engine to the wheels. Belt problems are a common headache.

  • Belt Slippage: Belt slippage can occur when the belt is worn, contaminated with oil or grease, or the CVT system is not properly adjusted.
  • Belt Breakage: Extreme stress or improper maintenance can cause the belt to break, leaving you stranded.

What to do: Regularly inspect the belt for wear and replace it according to the manufacturer's recommendations. Keep the CVT system clean and free of oil or grease. Ensure the CVT system is properly adjusted. Consider carrying a spare belt and the tools needed to replace it on the trail.

Electrical Gremlins: When the Lights Go Out and the Engine Stalls

Electrical problems can be frustrating and difficult to diagnose. The XR 700, like many ATVs, can experience its share of electrical gremlins.

Battery Issues: A weak or dead battery is a common problem.

  • Old Battery: Batteries have a limited lifespan. Over time, they lose their ability to hold a charge.
  • Loose Connections: Loose battery terminals can prevent the battery from charging properly.
  • Parasitic Drain: A parasitic drain occurs when an electrical component continues to draw power even when the ATV is turned off.

What to do: Test the battery regularly and replace it if it's weak or not holding a charge. Clean and tighten the battery terminals. Check for parasitic drains by using a multimeter to measure the current draw when the ATV is turned off. If you find a parasitic drain, identify and repair the faulty component.

Stator Failure: The stator generates electricity to charge the battery and power the electrical system.

  • Overheating: Excessive heat can damage the stator windings.
  • Short Circuits: Short circuits in the electrical system can overload the stator.

What to do: Regularly inspect the stator wiring for damage. Avoid overloading the electrical system with aftermarket accessories. If you suspect a stator failure, have it tested by a qualified mechanic.

Wiring Harness Problems: The wiring harness connects all the electrical components.

  • Corrosion: Corrosion can damage the wiring and connectors, leading to electrical problems.
  • Broken Wires: Wires can break due to vibration or abrasion.

What to do: Regularly inspect the wiring harness for damage. Clean and protect the connectors with dielectric grease. Repair any broken wires.

Suspension and Steering: Keeping You on Track

Properly functioning suspension and steering are essential for a comfortable and safe ride.

Worn Bushings: The suspension components rely on bushings to provide a smooth and controlled ride.

  • Lack of Lubrication: Insufficient lubrication can cause the bushings to wear prematurely.
  • Exposure to the Elements: Exposure to mud, water, and dirt can accelerate bushing wear.

What to do: Regularly lubricate the suspension bushings with a quality grease. Inspect the bushings for wear and replace them as needed.

Loose Steering Components: Loose steering components can cause wandering and make it difficult to control the ATV.

  • Worn Tie Rod Ends: Tie rod ends connect the steering linkage to the wheels. If they become worn, they can cause excessive play in the steering.
  • Loose Ball Joints: Ball joints connect the suspension components to the wheels. If they become loose, they can cause excessive play in the steering.

What to do: Regularly inspect the steering components for wear and looseness. Replace worn tie rod ends and ball joints as needed.
