Compatibility
The IMAYCC 80cc engine kit is suitable for most 26-28 inch wheeled bicycles with V-frames. This includes mountain bikes, cruisers, and road bikes. Ensure there is at least 10 inches of clearance between the bottom bracket and the top bar of the bicycle frame for proper installation.

Fuel Tank Installation
The 2.5L fuel tank requires careful installation to prevent leaks. Ensure the leak-proof gasket is properly seated. The fuel valve has two positions: UP for OFF and DOWN for ON. Always close the fuel valve when parking the bicycle.

Wiring Connections
Follow these steps for connecting the electrical wires:
- Connect the blue wire to the blue wire.
- Connect the black wire to the black wire.
- The white wire from the magnetic coil does not need to be connected. It should be wrapped with electrical tape for insulation.

Operating Instructions
Fuel Mixing Ratio
The engine requires a specific mixture of 90# gasoline and 2-stroke engine oil.
- New Equipment: 16:1 (Gasoline to Oil)
- Run-in Period (after 500km): 20:1 (Gasoline to Oil)
Ensure the fuel and 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 start the engine. Refer to the throttle and clutch lever instructions for proper engagement and disengagement.
Break-in Period
During the initial break-in period, it is recommended to use a slightly richer fuel mixture (e.g., 30:1 for the first three full tanks) and vary throttle settings. Avoid prolonged high-speed operation during this time to allow engine components to seat properly. Regularly check and tighten all nuts and bolts, as vibrations can cause them to loosen during this period.
Maintenance
Regular maintenance is crucial for the longevity and performance of your engine kit.
- Fuel Lines: The small fuel lines can harden over time. Replace them after each season of riding, or sooner if the bicycle sits for extended periods, to prevent leaks.
- Chain: The included chain is a 415 heavy-duty chain. Ensure it is properly tensioned and lubricated. If you need to shorten the chain, note that it is larger than standard bike chains and may require specific tools or methods for removal of links.
- Fasteners: Periodically check and tighten all nuts, bolts, and mounting hardware, especially after the break-in period, to prevent components from vibrating loose. Using a torque wrench for critical hardware is recommended.
- Carbon Buildup: If the engine shows signs of carbonization or soot buildup, adding a small amount (e.g., a couple of tablespoons) of Automatic Transmission Fluid (ATF) to the fuel and running it until dry can help clean the engine.
- Engine Mounts: To reduce vibration and stress on the engine and bike frame, consider placing cut pieces of tire inner tube between the engine mounts and the bicycle frame.
Troubleshooting
This section addresses common issues you might encounter.
- Clutch Engagement Issues: If the clutch does not engage or disengage properly, check the clutch engagement rod for wear or insufficient length. Ensure the clutch cable is correctly adjusted and lubricated.
- Muffler Detachment: Ensure the muffler is securely fastened. Vibrations can cause it to loosen. Regular checks are advised.
- Engine Not Starting: Verify fuel mixture, spark plug condition, and CDI ignition connections. Ensure the fuel valve is open.
- Vibration-Related Loosening: Regularly inspect all fasteners. Components like engine mounts and chain tensioners are particularly susceptible to loosening due to engine vibration.
Many common issues and solutions can be found through online searches for 80cc engine kits, as most share similar maintenance and repair processes.
