Operating Instructions

Fuel Mixture

The engine operates on a mixture of 90# gasoline and engine oil. The mixing ratio is critical for engine longevity and performance:

• For new equipment (first 500km): 16:1 (Gasoline:Engine Oil)
• After run-in period (after 500km): 20:1 (Gasoline:Engine Oil)

Ensure the fuel and engine oil are thoroughly mixed before adding to the fuel tank.

Starting the Engine

The engine is started using the foot pedal. Engage the clutch, pedal the bicycle to gain some speed, then release the clutch to engage the engine. The CDI ignition system will initiate combustion.

Performance and Usage

The 100cc engine provides a power output of 2kw at 6500rpm, allowing for faster riding speeds. When driving on smooth roads, a speed of 35-40km/h is recommended, with a maximum speed limit of 50km/h. The fuel consumption is approximately 2.5L per 100km.

Maintenance

Regular maintenance is essential to ensure the longevity and reliable operation of your motorized bicycle. Always perform maintenance in a well-ventilated area and ensure the engine is cool.

• Pre-Ride Checks: Before each ride, inspect all bolts and connections for tightness. Vibrations from engine operation can cause components to loosen over time. Consider using thread locker on critical bolts, especially exhaust bolts, to prevent loosening.
• Spark Plug: Periodically check the spark plug for fouling and wear. Replace as necessary to ensure efficient ignition.
• Chain Tension: The drive chain tensioner may require periodic adjustment, particularly during the break-in period as the chain stretches. Maintain proper chain tension to prevent slipping and excessive wear.
• Fuel System: Regularly inspect fuel lines and connections for any signs of leaks. Ensure the fuel filter is clean.
• Carburetor: Keep the carburetor clean and ensure it is securely mounted to prevent air leaks.

Troubleshooting

This section addresses common issues that may arise during the installation or operation of your engine kit. Many problems can be resolved with careful inspection and adjustment.

• Engine Does Not Start:
  • Check fuel supply: Ensure the fuel tank has the correct fuel mixture and the fuel valve is open.
  • Spark plug: Verify the spark plug is clean and producing a spark. Replace if necessary.
  • Carburetor: Ensure the carburetor is securely tightened and not leaking fuel. A loose carburetor can prevent proper starting.
  • Wiring: Double-check all electrical connections as per the wiring diagram.
• Fuel Leaks:
  • Fuel Tank: Ensure the fuel tank cap is tight and the fuel valve is closed when not in use. Inspect the tank for cracks or loose fittings.
  • Carburetor: Check all carburetor gaskets and connections. Tighten any loose screws.
• Chain Slipping/Coming Off:
  • Chain Alignment: Ensure the engine, sprocket, and bicycle chain are perfectly aligned. Misalignment can cause the chain to slip.
  • Chain Tension: Adjust the chain tensioner to maintain appropriate chain tautness.
  • Sprocket Installation: Verify the rear sprocket is securely mounted and properly aligned with the wheel.
• Excessive Vibration/Noise:
  • Loose Components: Re-check all mounting bolts for the engine, exhaust, and other components.
  • Engine Mounts: Ensure engine mounts are secure and not damaged.
• Poor Performance (e.g., 4-stroking, fouled spark plugs):
  • Fuel Mixture: Verify the fuel-to-oil ratio is correct for the engine's run-in status.
  • Carburetor Adjustment: The carburetor may require fine-tuning. Consult online resources or a professional if unsure.

For persistent issues, it is recommended to consult a qualified mechanic or refer to additional online resources and communities dedicated to motorized bicycle kits.
