4. Operating Instructions

4.1 Fueling

• Use fresh, unleaded gasoline with an octane rating of 87 or higher.
• The fuel tank capacity is approximately 1 gallon.
• Always refuel in a well-ventilated area with the engine off and cool.

4.2 Starting the Engine

1. Ensure the fuel valve is in the 'ON' position.
2. If the engine is cold, engage the choke.
3. Place the bike in neutral.
4. Use the kick start lever with a firm, swift motion. Do not 'feather' the kick start.
5. Once the engine starts, gradually disengage the choke as the engine warms up.
6. If the engine does not start after several kicks, check the engine kill switch, fuel supply, and spark plug.

4.3 Semi-Automatic Transmission

The DB14 features a semi-automatic transmission, meaning there is no clutch lever. Shifting gears is done by pressing the gear shifter with your foot.

• To shift up, press the shifter down.
• To shift down, lift the shifter up.
• Practice shifting at low speeds in a safe, open area until comfortable.

4.4 Braking

The bike is equipped with front and rear hydraulic disc brakes.

• The front brake is operated by the lever on the right handlebar.
• The rear brake is operated by the foot pedal on the right side.
• Apply both brakes smoothly and progressively for effective stopping. Avoid sudden, hard braking, especially on loose surfaces.

4.5 Engine Kill Switch

A red engine kill switch is located on the handlebar. Pressing this switch will immediately cut power to the engine, stopping the bike. Use this for emergencies or when shutting down the engine.

5. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your dirt bike.

5.1 Engine Oil Change

• Change the engine oil after the first hour of operation (break-in period), then every 10-15 hours of riding or every 3 months, whichever comes first.
• Use recommended motorcycle engine oil (e.g., 10W-40).
• Refer to the engine diagram for drain plug and fill cap locations.

5.2 Chain Maintenance

• Inspect the drive chain for proper tension and lubrication before each ride.
• Adjust chain tension as needed; there should be approximately 0.5-1 inch of slack.
• Clean and lubricate the chain regularly with specialized chain lubricant.

5.3 Tire Inspection and Pressure

• Check tire pressure before each ride. Refer to the tire sidewall for recommended pressure.
• Inspect tires for wear, cuts, or punctures. Replace damaged tires immediately.

5.4 Fastener Checks

• Regularly check all bolts, nuts, and fasteners for tightness, especially on critical components like handlebars, wheels, brakes, and suspension.
• Loose fasteners can lead to component failure and unsafe operation.

5.5 General Cleaning

• Clean the bike after each ride, especially if ridden in muddy or dusty conditions.
• Avoid high-pressure washing directly on electrical components, bearings, or seals.

6. Troubleshooting

This section addresses common issues you might encounter with your X-PRO 110cc DB14 Dirt Bike.

6.1 Engine Does Not Start

• No Fuel: Check fuel level and ensure the fuel valve is open.
• Engine Kill Switch: Ensure the engine kill switch is in the 'RUN' position.
• Choke: Apply choke if the engine is cold.
• Spark Plug: Inspect the spark plug for fouling or damage. Replace if necessary.
• Ignition System: If the spark plug is good, issues might stem from the CDI, stator, or ignition coil. These components may require professional diagnosis.

6.2 Engine Dies Frequently / Runs Rough

• Fuel Quality/Supply: Ensure fresh fuel and clear fuel lines. Check for blockages in the fuel filter or carburetor.
• Air Filter: A dirty air filter can restrict airflow. Clean or replace as needed.
• Carburetor Adjustment: The carburetor may need adjustment for optimal fuel-air mixture. This is often best done by a professional.

6.3 Shifting Difficulties

• Chain Tension: Incorrect chain tension can affect shifting. Adjust as per maintenance guidelines.
• Transmission Fluid: Ensure proper transmission fluid levels (if applicable, check manual for specific fluid type).
• Linkage: Inspect the shift linkage for obstructions or damage.

6.4 Oil Leakage

• Drain Plug/Fill Cap: Check if the oil drain plug and fill cap are securely tightened.
• Gaskets/Seals: Inspect engine gaskets and seals for signs of wear or damage. Leaks from these areas may require professional repair.

6.5 Flat Tire

• Puncture: Locate the puncture and repair or replace the inner tube.
• Valve Stem: Check the valve stem for leaks.
