• Point 2: Black wire and black wire connection.
• Point 3: White wire does not need to be connected; it should be wrapped with electrical tape for insulation.

4. Operating Instructions

4.1 Fuel Mixture

For optimal performance and engine longevity, use 90# fuel mixed with 2-stroke engine oil. The mixing ratio is critical:

• Initial Break-in Period (first 500km): 16:1 (fuel to oil ratio).
• After Break-in Period: 20:1 (fuel to oil ratio).

Always mix the fuel and oil thoroughly before adding it to the fuel tank. Ensure the fuel valve is closed when parking the bicycle to prevent leaks.

4.2 Engine Start and Operation

The engine features CDI ignition and a foot pedal start mechanism. Once installed and fueled, engage the clutch and pedal the bicycle to gain momentum, then release the clutch to start the engine. Familiarize yourself with the throttle control for speed regulation.

4.3 Performance Guidelines

When driving on a smooth road, maintain a speed of 35-40 km/h. The maximum speed limit for this engine is 50 km/h. The typical fuel consumption is approximately 2.5 liters per 100 km.

5. Maintenance

Regular maintenance is essential for the longevity and reliable operation of your engine kit.

5.1 Routine Checks

• Fasteners: Periodically check all nuts and bolts for tightness. Vibrations can cause components to loosen. Applying thread-locking compound (Loctite) to critical fasteners can help prevent loosening.
• Chain Tension: The drive chain tensioner may require periodic adjustment, especially during the initial break-in period as the chain stretches. Ensure proper chain tension to prevent derailment or damage.
• Spark Plug: Inspect and replace the spark plug as needed. A new spark plug may be required after the break-in period or if starting issues occur.
• Fuel System: Regularly check fuel lines and connections for leaks. Ensure the fuel filter is clean.
• Wiring: Inspect wiring for any signs of wear, melting, or damage, particularly near hot components like the muffler. Reroute or insulate wires if they are in contact with hot surfaces.

5.2 Fuel Mixture Adherence

Strictly follow the recommended fuel-to-oil mixing ratios (16:1 for break-in, 20:1 thereafter) to ensure proper engine lubrication and prevent premature wear.

6. Troubleshooting

This section addresses common issues you might encounter with your engine kit.

6.1 Engine Not Starting or Running Poorly

• Fuel Supply: Check if the fuel tank has sufficient fuel and the fuel valve is open. Ensure the fuel line is not kinked and the fuel filter is clean.
• Spark Plug: Inspect the spark plug for fouling or damage. Clean or replace if necessary.
• Magneto Waterlogging: In wet weather, the magneto can become waterlogged, preventing the engine from starting. Consider sealing the magneto cover to prevent water ingress.
• Carburetor: Ensure the carburetor is clean and properly adjusted.

6.2 Loose or Damaged Components

• Exhaust System: If the exhaust becomes loose or falls off, check the mounting bolts and threads. Re-secure with thread-locking compound if possible.
• Chain Tensioner: A loose chain tensioner can cause the chain to interfere with the rear spokes. Ensure it is securely fastened and adjusted correctly.
• General Hardware: If you experience issues with bolts stripping or loosening frequently, consider replacing them with higher-quality hardware from a local store.

6.3 Electrical Issues

• Melting Wires: If wires are running too close to the muffler or other hot engine parts, they can melt. Reroute wires away from heat sources or use heat-resistant insulation.
• CDI Ignition: Ensure all CDI ignition connections are secure and free from corrosion.
