However, if you install the new sprocket, you are rest assured that it is durable and is compatible with other parts that you bought along with the kit. To fit the sprocket, this is the best way you can do it.
    1. On the rear wheel of the bike, you’ll find two nuts. These should be opened using a ring spanner.
    2. Before you install the new sprocket, it is best to put aside the chain from sprocket found in the rear wheel.
    3. Separate the rear wheel from the bike for the meantime.
    4. Put the rubber bush in the tire’s shaft, which can be found on both sides.
    5. Use the new sprocket that is included in the kit you bought and attach it to the shaft’s rear wheel.
    6. Insert the nine screws using a screwdriver
    7. To remove screw easier, place a C-section washer. The most recommended type is the one made from steel as it is corrosive resistant.
    8. Use the nut to tighten the screw.
    9. Re-fit the wheel back to the bicycle.

  2. Even before you rotate it, don’t forget to install the sparks plug. This can be installed on the upper side. When you install the spark plug in the bike engine, it will allow the bike to start. Without it, the bike will not move.
  3. Installing a clutch decreases the risk of injury and accident. This should be mounted on the left side handle of your bike. The clutch is a vital motorbike part of installing as it is used to engage and disengage the engine.
  4. Even if the bike has installed the motor, you should not forget about the chains. In between the engine shaft sprocket and the bicycle sprocket, the string should be snugged in and use a master link to connect the chains.
  5. If you won’t be able to tighten the chain installed, it is best to use the chain tensioner. This will help in tightening the chains if it is pulled.
  6. To increase the supply of fuel for your custom bike, you need to use the accelerator bar. This can be installed on the handlebar, preferably at the right. To set up an accelerator, this is what you can do:
    • Join the carburetor’s other end with the accelerators.
    • Remove the bicycle brake on the right side.
    • Replaced the brake found at the side with the accelerator
    • To avoid movable parts in your bike, tighten the screws.
  1. After installing the accelerator, attach the carburetor to the manifold of the engine but pay attention to the cables as it should be in a straight position.
  2. Set up the gas tank above your bike’s straight bar and tighten it with a bracket.
  3. Using the tube, connect the gas tank’s exhaust manifold with the carburetor
  4. To have an exhaust structure for the bike, the muffler is attached to the exhaust engine with a bolt. However, make sure that the muffler attached has a gasket.
  5. Insert fuel to your tank, followed by 2T oil, which will lubricate the piston and the engine.
