Linhai Bighorn 28 Problems

The Linhai Bighorn 28, while often touted as an affordable entry-level ATV, can present its owners with a frustrating array of issues. From persistent mechanical gremlins to design flaws that impact reliability, understanding these potential problems is crucial before making a purchase, and vital for owners seeking to keep their machines running. Knowing common pitfalls empowers you to make informed decisions about maintenance, modifications, and ultimately, whether the Bighorn 28 is the right ATV for your needs.

Starting Problems: When Your Bighorn Refuses to Roar

One of the most frequently reported issues with the Linhai Bighorn 28 is difficulty starting. This can manifest in several ways, leaving owners stranded and frustrated. Let's break down the potential culprits:

Battery Blues: Often, a weak or failing battery is the prime suspect. The Bighorn 28, like many ATVs, relies on a healthy battery for starting, especially in colder weather. Regular battery maintenance, including checking electrolyte levels (if applicable) and ensuring a full charge, is essential. Consider investing in a battery tender to keep the battery topped up during periods of inactivity.
Carburetor Conundrums: The Bighorn 28 utilizes a carburetor, a relatively simple but sometimes temperamental fuel delivery system. Over time, the carburetor can become clogged with debris, leading to poor fuel delivery and starting problems. Regular cleaning of the carburetor, including the jets and float bowl, is a necessity. You might also consider using a fuel stabilizer in the gasoline, especially if the ATV is stored for extended periods.
Spark Plug Snafus: A faulty spark plug can also prevent the engine from starting. Check the spark plug for fouling, damage, or excessive wear. Replacing a worn or fouled spark plug is a simple and inexpensive task that can often resolve starting issues.
Electrical Gremlins: The Bighorn 28's electrical system, while generally straightforward, can be prone to issues. Check the ignition switch, starter solenoid, and wiring for any signs of damage or corrosion. A multimeter can be used to test the continuity of the circuits and identify any open circuits or shorts. Don't overlook the safety interlocks (like the brake lever sensor), as a malfunctioning interlock can prevent the engine from starting.

Suspension Woes: A Bumpy Ride Ahead?

The Bighorn 28's suspension, while adequate for light-duty use, is often cited as a weak point. Owners frequently report issues with the shocks and bushings.

Shocking Performance: The stock shocks are often criticized for being too stiff and providing a harsh ride. This can be particularly noticeable on rough terrain. Upgrading to aftermarket shocks can significantly improve ride quality and handling. Consider shocks with adjustable preload and damping to fine-tune the suspension to your specific needs and riding style.
Bushing Breakdown: The bushings in the suspension components are prone to wear and tear, leading to sloppy handling and excessive play. Regularly inspect the bushings for cracks, wear, and looseness. Replacing worn bushings with polyurethane bushings can improve durability and handling.
Alignment Issues: Improper wheel alignment can also contribute to poor handling and premature tire wear. Ensure that the wheels are properly aligned according to the manufacturer's specifications.

Braking Blues: Stopping Power Concerns

Reliable brakes are crucial for safety, and the Bighorn 28's braking system can sometimes be a source of concern.

Weak Stopping Power: Some owners report that the brakes lack sufficient stopping power, especially when carrying heavy loads or riding on steep terrain. Inspect the brake pads for wear and replace them as needed. Ensure that the brake lines are free of leaks and that the brake fluid is at the proper level. Bleeding the brakes to remove any air bubbles in the system can also improve braking performance.
Brake Fade: Brake fade, a reduction in braking power due to overheating, can occur during prolonged or heavy braking. This is more common in machines used for demanding tasks. Consider upgrading to higher-performance brake pads or rotors to improve heat dissipation and reduce brake fade.
Parking Brake Problems: The parking brake mechanism can sometimes be finicky and prone to malfunction. Ensure that the parking brake cable is properly adjusted and that the mechanism is free of corrosion or debris.

Engine Issues: Keeping the Heart Pumping

While the Linhai engine is generally considered reliable for its displacement, certain issues can arise.

Overheating: Overheating can occur, especially during hot weather or when the ATV is used for prolonged periods at high speeds. Ensure that the radiator is clean and free of debris. Check the coolant level and top it off as needed. Inspect the cooling fan to ensure that it is functioning properly.
Oil Leaks: Oil leaks can develop over time, particularly around the valve cover, oil filter, and drain plug. Regularly inspect these areas for leaks and tighten any loose bolts or fittings. Replace any worn seals or gaskets.
Valve Adjustment: Improper valve adjustment can lead to poor engine performance, including reduced power and increased fuel consumption. Check the valve clearance according to the manufacturer's specifications and adjust as needed.

Other Common Complaints: A Mixed Bag of Troubles

Beyond the major systems, several other issues are frequently reported by Bighorn 28 owners.

Plastic Problems: The plastic body panels are often criticized for being brittle and prone to cracking, especially in cold weather. Handle the plastic panels with care and avoid subjecting them to excessive stress.
Rust and Corrosion: The Bighorn 28, like many ATVs, is susceptible to rust and corrosion, especially in areas with harsh weather conditions. Regularly wash and wax the ATV to protect the metal surfaces. Apply a rust inhibitor to vulnerable areas.
Electrical Connector Issues: The electrical connectors can be prone to corrosion, leading to intermittent electrical problems. Apply dielectric grease to the connectors to prevent corrosion and ensure reliable electrical connections.

Modifications and Upgrades: Addressing the Shortcomings

Many Bighorn 28 owners choose to address the ATV's shortcomings through modifications and upgrades. Some popular modifications include:

Suspension Upgrades: Replacing the stock shocks with aftermarket shocks is a common upgrade to improve ride quality and handling.
Tire Upgrades: Upgrading to more aggressive tires can improve traction and performance in off-road conditions.
Carburetor Jetting: Adjusting the carburetor jetting can improve engine performance and fuel efficiency.
Exhaust Upgrades: Installing an aftermarket exhaust system can increase horsepower and improve the engine's sound.
Lighting Upgrades: Upgrading to LED lighting can improve visibility and safety.

Preventative Maintenance: The Key to Longevity

Regular preventative maintenance is essential for keeping the Linhai Bighorn 28 running smoothly and avoiding costly repairs. Some key maintenance tasks include:

Oil Changes: Change the engine oil and filter regularly according to the manufacturer's specifications.
Air Filter Cleaning: Clean the air filter regularly to ensure proper airflow to the engine.
Spark Plug Replacement: Replace the spark plug periodically to maintain optimal engine performance.
Brake Inspection: Inspect the brakes regularly and replace the brake pads as needed.
Tire Pressure: Maintain proper tire pressure to ensure optimal handling and tire life.
Lubrication: Lubricate all moving parts regularly to prevent wear and tear.
Coolant Flush: Flush the cooling system periodically to prevent corrosion and maintain proper cooling.
