From Pedals to Power—In Just a Few Hours!

“ I bought this kit 6 months ago and it was the first one I’ve ever installed and it was definitely worth it. I just upgraded to a new motor but the original motor still runs amazing. The directions are very thorough and as long as you take care of it it will run great.” - Larry S.

🌟HOW TO USE

     1. Prep the Bike

• Choose a sturdy 26” steel-frame bike (preferably with a V-frame and no rear suspension).
  
• Remove the chain guard, fenders, or accessories that may interfere with the installation.
  
• Deflate the rear tire to make mounting the rear sprocket easier.
  
  

     2. Install the Rear Sprocket

• Position the rubber isolator pads on both sides of the rear spokes.
  
• Align the sprocket over the hub and secure it using the included bolts and nuts.
  
• Make sure the sprocket is centered and does not wobble.
  
  

     3. Mount the Engine

• Place the engine in the center of the V-frame triangle.
  
• Use the U-bolts and mounting bracket to secure the engine to the frame.
  
• Ensure the engine is level and tightly fastened.
  
  

     4. Attach the Chain

• Fit the chain over the engine sprocket and the rear wheel sprocket.
  
• Use the chain breaker tool to adjust length if needed.
  
• Install the chain tensioner on the rear stay and adjust for proper tension (about ½" slack).
  

     5. Install the Fuel Tank

• Mount the tank on the top tube using the metal brackets and rubber pads.
  
• Tighten the straps and connect the fuel line from the tank to the carburetor.
  
  

     6. Install the Carburetor and Air Filter

• Slide the carburetor onto the intake manifold and secure it with the clamp.
  
• Attach the air filter onto the carburetor.
  
  

     7. Connect the Throttle and Kill Switch

• Insert the throttle cable into the carburetor slide and route it to the throttle grip.
• Secure the throttle and kill switch to the handlebar.
  
• Connect the kill switch wires to the CDI unit.
  
  

     8. Wire the Ignition (CDI Box)

• Connect the spark plug wire to the spark plug.
  
• Plug the matching wires from the CDI unit to the engine magneto wires.
  
  • Blue to blue
    
  • Black to black
    
  • White (optional for lights or accessories)
    
    

     9. Install the Exhaust

• Mount the muffler to the cylinder exhaust port using the included bolts and gasket.
  
• Ensure clearance from pedals and the bike frame.
  
  

     10. Final Checks

• Check all bolts and connections for tightness.
  
• Fill the tank with a 16:1 or 20:1 gas-oil mix (break-in period).
  
• Test throttle, brakes, and clutch function before starting.
