The CFMoto Terralander 800, also known as the CFORCE 800 in some markets, is a popular ATV known for its powerful engine, decent features, and attractive price point. However, like any machine, it's not without its quirks and potential issues. Understanding these common problems can help you make an informed buying decision if you're considering one, or troubleshoot effectively if you already own one. Let's dive into the nitty-gritty of what Terralander 800 owners have reported.

What's the Buzz? Common Complaints About the Terralander 800

Before we get into the specifics, it's important to remember that online forums and reviews tend to amplify negative experiences. Many Terralander 800 owners are perfectly happy with their machines. However, awareness of potential issues is crucial for preventative maintenance and informed decision-making. Here are some of the most frequently discussed problems:

  • Electrical Gremlins: This is arguably the most common complaint. Owners report issues ranging from faulty sensors and flickering lights to complete electrical system failures.

  • CVT Clutch Issues: The Continuously Variable Transmission (CVT) is a complex system, and the Terralander 800's CVT seems prone to premature wear, belt slippage, and jerky engagement.

  • Suspension Woes: While the suspension offers decent travel, some owners find it too stiff, especially at lower speeds. Bushing wear and shock absorber leaks are also reported.

  • Cooling System Concerns: Overheating, particularly in hot weather or during demanding tasks, is another recurring problem. Issues can stem from radiator clogs, faulty fans, or insufficient coolant flow.

  • Build Quality and Component Durability: While the Terralander 800 offers a lot of bang for your buck, some owners question the long-term durability of certain components, particularly plastic body panels and some drivetrain parts.

Decoding the Electrical Mysteries

Electrical problems in the Terralander 800 can manifest in various ways. Here's a closer look:

  • Sensor Failures: Oxygen sensors, throttle position sensors (TPS), and other engine management sensors can fail prematurely, leading to poor performance, error codes, and even engine stalling. Often, replacing the sensor with a higher-quality aftermarket option can resolve the issue permanently.

  • Wiring Harness Issues: The wiring harness can be vulnerable to damage from vibration, abrasion, and moisture. Look for frayed wires, loose connections, and corroded terminals. Applying dielectric grease to connections can help prevent corrosion.

  • Battery Drain: Some owners report unexplained battery drain, even when the ATV is not in use. This could be caused by a parasitic draw from a faulty accessory or a failing voltage regulator.

  • Lighting Problems: Headlights and taillights can flicker or fail due to faulty bulbs, loose connections, or wiring issues. Upgrading to LED bulbs can improve brightness and reliability.

To diagnose electrical problems, a multimeter is your best friend. Learn how to use it to check voltage, continuity, and resistance. A service manual with wiring diagrams is also invaluable.

Taming the CVT: Clutch and Belt Blues

The CVT is the heart of the Terralander 800's transmission, and its performance is crucial for smooth acceleration and efficient power delivery. Here's what can go wrong:

  • Belt Slippage: This is a common symptom of a worn or contaminated belt. Slippage can cause jerky acceleration, loss of power, and excessive heat buildup. Regular belt inspections and cleaning are essential.

  • Clutch Engagement Problems: The clutch may engage too harshly or too softly, leading to poor acceleration or difficulty climbing hills. Adjusting the clutch weights or replacing worn clutch components can improve engagement.

  • Premature Wear: The CVT belt and clutch components can wear out prematurely if the ATV is used aggressively or in demanding conditions. Using a high-quality aftermarket belt and performing regular maintenance can extend the life of the CVT.

  • Roller and Slide Wear: The clutch rollers and slides within the CVT are subject to wear, which can affect the clutch's ability to engage and disengage smoothly. Regular inspection and replacement of these components is crucial for maintaining proper CVT function.

Consider upgrading to a performance CVT clutch kit for improved durability and performance. These kits often include stronger springs, weights, and other components designed to handle the rigors of off-road riding. Also, ensure the CVT housing is properly sealed to prevent water and debris from entering.

Smoothing Out the Ride: Suspension Solutions

While the Terralander 800's suspension is adequate for general use, some owners find it lacking in certain areas:

  • Stiff Ride: The suspension can feel too stiff, especially at lower speeds. Adjusting the preload on the shocks can help soften the ride. Consider upgrading to aftermarket shocks with adjustable damping for a more customized ride.

  • Bushing Wear: The suspension bushings are prone to wear, leading to excessive play and a sloppy feel. Replacing worn bushings with polyurethane bushings can improve handling and durability.

  • Shock Absorber Leaks: The shock absorbers can leak oil, reducing their damping performance. Replacing leaking shocks is the best solution. Consider upgrading to aftermarket shocks with improved seals and construction.

  • A-Arm Issues: Bent A-arms can occur from impacts. Regularly inspect the A-arms for any damage or bending, and replace as needed.

Properly lubricating the suspension components can help prevent wear and maintain a smooth ride. Use a high-quality grease specifically designed for ATV suspensions.

Keeping Cool: Overheating Prevention

Overheating can be a serious problem for the Terralander 800, especially in hot climates. Here's how to keep your engine cool:

  • Radiator Cleaning: The radiator can become clogged with mud, dirt, and debris, restricting airflow and reducing cooling efficiency. Regularly clean the radiator with a garden hose and a soft brush. Avoid using a pressure washer, as it can damage the delicate fins.

  • Coolant Level: Check the coolant level regularly and top it off as needed. Use a coolant specifically designed for ATVs.

  • Fan Operation: Ensure the cooling fan is operating properly. If the fan is not turning on when the engine is hot, check the fan motor, fan switch, and wiring.

  • Thermostat Function: A faulty thermostat can prevent coolant from circulating properly, leading to overheating. Replacing the thermostat is a relatively simple and inexpensive repair.

Consider adding an aftermarket radiator guard to protect the radiator from damage. Also, avoid running the engine at high RPMs for extended periods in hot weather.

Addressing Build Quality Concerns

While the Terralander 800 offers good value for the money, some owners have raised concerns about the durability of certain components:

  • Plastic Body Panels: The plastic body panels can be brittle and prone to cracking, especially in cold weather. Be careful when handling the body panels and avoid exposing them to extreme temperatures.

  • Drivetrain Components: Some owners have reported premature wear of drivetrain components, such as axles and bearings. Regular maintenance and lubrication can help extend the life of these components.

  • Rust: Rust can be a problem, especially in areas with harsh winters or coastal climates. Regularly wash and wax your ATV to protect it from rust. Apply a rust inhibitor to exposed metal surfaces.

  • Hardware: Some hardware components, like bolts and fasteners, can be prone to corrosion or stripping. Consider replacing these with stainless steel hardware for improved durability and resistance to corrosion.

Taking good care of your Terralander 800 and performing regular maintenance can help mitigate these build quality concerns.
