80cc Bike Motor Wiring Diagram

Riding a bicycle is a great way to enjoy the outdoors and get some exercise, but what if you could give your ride a little boost? With an 80cc bike motor, you can convert your ordinary bike into a motorized machine. But before you get started, you need to know how to wire your motor properly. In this article, we will provide you with a complete 80cc bike motor wiring diagram, along with some frequently asked questions to help you get started.

Introduction to 80cc Bike Motor Wiring Diagram

Wiring your 80cc bike motor can be a bit daunting if you’ve never done it before. But don’t worry, because with this wiring diagram, you’ll be able to easily connect all the necessary components, including the engine, CDI, magneto, coil, spark plug, and kill switch.

Before we dive into the details, it’s important to understand the basics. A CDI (Capacitor Discharge Ignition) is used to create a spark in the cylinder, which ignites the fuel and air mixture. The magneto (generator) creates electricity to power the CDI, while the coil enhances the voltage. The spark plug ignites the fuel and air mixture in the cylinder, and the kill switch is used to stop the engine.

Now that you have a basic understanding of the components, let’s take a look at the wiring diagram.

80cc Bike Motor Wiring Diagram

The following wiring diagram will help you wire your 80cc bike motor properly:

Wire Color Component Connection
Black Engine Ground
Green CDI Ground
Yellow CDI Power
Red Magneto Power
Blue CDI Power
Black/White CDI Kill Switch
Green/White Coil Ground
Red/White Coil Power
Black/Yellow Spark Plug Ground
Red/Yellow Spark Plug Power

Before you start connecting the wires, make sure you have all the necessary tools, including wire strippers, electrical tape, and a multimeter (to test the connections). Once you have the tools, follow these steps:

Step 1: Connect the Engine

The black wire from the engine should be connected to ground (usually the frame of the bike).

Step 2: Connect the CDI

The green wire from the CDI should be connected to ground (usually the frame of the bike), while the yellow wire should be connected to power (usually the red wire from the magneto).

The blue wire from the CDI should also be connected to power (usually the red wire from the magneto). This wire provides power to the CDI.

The black/white wire from the CDI should be connected to the kill switch. This wire is used to stop the engine.

Step 3: Connect the Magneto

The red wire from the magneto should be connected to power (usually the positive terminal of the battery).

Step 4: Connect the Coil

The green/white wire from the coil should be connected to ground (usually the frame of the bike), while the red/white wire should be connected to power (usually the red wire from the magneto).

Step 5: Connect the Spark Plug

The black/yellow wire from the spark plug should be connected to ground (usually the frame of the bike), while the red/yellow wire should be connected to power (usually the red wire from the magneto).

FAQ

1. How do I know if I wired my 80cc bike motor correctly?

You can use a multimeter to test the connections and ensure there are no shorts or open circuits. You can also test the spark plug to see if it is firing properly.

2. What do I do if my motor won’t start?

Check the wiring diagram to make sure all the connections are correct. If everything looks good, check the spark plug to see if it is firing. If it is not firing, you may need to replace the CDI or coil.

3. How do I maintain my 80cc bike motor?

You should regularly check the oil level and change it when necessary. You should also check the spark plug and clean or replace it if necessary. Additionally, you should check the air filter and clean or replace it if necessary.

4. How fast can an 80cc bike motor go?

An 80cc bike motor can reach speeds of up to 40 mph, depending on the weight of the rider and the terrain.

5. Is it legal to ride an 80cc bike motor on the road?

It depends on the state or country where you live. In some places, a bike motor is considered a moped and requires a license and registration. In other places, it may be considered a bicycle and does not require any special license or registration.

Conclusion

Wiring your 80cc bike motor may seem complicated, but with this wiring diagram and the FAQs, you should be able to do it easily. Remember to double-check all the connections and test the spark plug before you try to start your motor. Once your bike is up and running, you’ll be able to enjoy a faster and more exciting ride!
