4. Guia d'instal·lació

The installation process requires basic hardware skills and tools. Refer to the video below for a visual guide. It is recommended to watch the entire video before starting the installation.

4.1. Comprovació de compatibilitat

This kit is suitable for most 26-28 inch wheeled bikes (mountain bikes, cruisers, motorcycles, road bikes) with V-frames. Ensure there is at least 10 inches of clearance between the bottom bracket and the top bar of the frame, especially for 26-inch bikes.

4.2. Instal·lació pas a pas

1. Step 1: Install the Sprocket (Video: 0:20 - 1:29)
   Remove the rear wheel. Disassemble the existing sprocket if necessary. Cut the rubber pads to fit the spokes. Place the rubber pads, sprocket, and mounting plates onto the wheel hub. Secure them with bolts and nuts, ensuring the sprocket is centered and tight. Reinstall the rear wheel.
2. Step 2: Installation of Engine and Carburetor (Video: 1:30 - 3:27)
   Install the spark plug into the engine cylinder head. Assemble the carburetor by inserting the throttle needle and spring into the throttle slide, then attach the throttle cable. Mount the carburetor onto the engine intake manifold. Position the engine within the bicycle frame's V-frame. Secure the engine using the provided mounting plates, bolts, and nuts. Ensure the engine is level and does not interfere with pedals or other bike components.
3. Step 3: Installation of Chain (Video: 3:28 - 6:06)
   Install the chain tensioner onto the bicycle frame. Route the drive chain from the engine sprocket to the rear wheel sprocket, passing through the chain tensioner. Adjust the chain length by marking and removing excess links using the chain breaker tool. Connect the chain ends with the master link. Adjust the chain tensioner to ensure proper chain tension.
4. Step 4: Installation of The Throttle Handle (Video: 6:07 - 6:59)
   Disassemble the throttle handle housing. Insert the throttle cable into the throttle mechanism. Mount the throttle handle onto the right handlebar. Secure the throttle handle housing with screws. Ensure the throttle operates smoothly and returns to the idle position when released.
5. Step 5: Installation of Clutch Lever and Clutch Cable (Video: 7:00 - 7:39)
   Attach the clutch cable to the clutch lever. Mount the clutch lever onto the left handlebar. Route the clutch cable to the engine's clutch arm. Connect the clutch cable to the clutch arm, ensuring proper tension for smooth clutch engagement and disengagement.
6. Step 6: Installing The Ignition (Video: 7:40 - 8:18)
   Mount the CDI ignition unit to a suitable location on the bicycle frame, typically using zip ties or clamps. Connect the ignition wires: blue to blue, black to black. The white wire from the magnetic coil does not need to be connected; insulate it with electrical tape. Connect the spark plug cap to the spark plug.

7. Step 7: Installation of Fuel Tank, Exhaust, and Chain Cover (Video: 8:19 - 1:18:00)
   Install the fuel tank onto the top tube of the bicycle frame using the provided mounting hardware. Attach the fuel valve and fuel filter to the fuel tank. Connect the fuel line from the fuel filter to the carburetor. Install the exhaust pipe onto the engine cylinder, securing it with bolts. Attach the chain cover to protect the drive chain, ensuring it does not interfere with moving parts.

5. Instruccions de funcionament

5.1. Fuel Mixing

This is a 2-stroke engine and requires a specific gasoline-to-engine oil mixture. Use 90# gasoline.

• New Equipment: 16:1 (Fuel:Engine Oil)
• After Run-in Period (after 500km): 20:1 (Fuel:Engine Oil)

Mix thoroughly before adding to the fuel tank. Always close the fuel valve when parking the bicycle.

5.2. Arrencada del motor

1. Obriu la vàlvula de combustible.
2. Engage the choke (if cold starting).
3. Desenganxar l'embragatge.
4. Pedal the bicycle to gain some speed (approx. 5-10 mph).
5. Slowly release the clutch lever. The engine should engage and start.
6. Un cop el motor arrenqui, desconnecteu gradualment l'estrangulador.

5.3. Equitació

• Control speed using the throttle handle.
• Use the clutch for smooth starts and stops.
• Maintain a speed of 35-40 km/h for optimal fuel consumption (2.5L per 100km). Maximum speed limit is 50 km/h.

5.4. Aturar el motor

• Enganxa l'embragatge.
• Press the kill switch to turn off the engine.
• Close the fuel valve when the engine is off or the bike is parked.
