1. Add an aftermarket exhaust system. This will help improve the flow of exhaust gases and increase power.
2. Install a high-performance air filter. This will allow your engine to breathe more air and produce more power.
3. Rejet the carburetor. This will help ensure that your engine is getting the right amount of fuel and air for maximum power.
4. Install a larger rear sprocket. This will give your bike more torque and acceleration.
5. Remove the airbox lid. This will allow more air to flow into the engine and increase power.
6. Install a performance spark plug. This will help improve combustion and increase power.
7. Advance the timing. This will help the engine produce more power at higher RPMs.
Please note that some of these modifications may require you to make other changes to your bike, such as rejetting the carburetor or changing the sprockets. It's also important to keep in mind that making your bike faster may also make it less fuel-efficient or more difficult to ride.
