1. Increase the compression ratio. This can be done by installing a higher-compression piston or cylinder head.
2. Install a larger carburetor. This will allow more fuel to enter the engine, which can result in more power.
3. Modify the exhaust system. A freer-flowing exhaust system can help the engine breathe better, which can also lead to more power.
4. Add a power valve. A power valve can help improve the engine's performance at high RPMs.
5. Re-jet the carburetor. This is necessary whenever you make any changes to the engine that affect the fuel mixture.
6. Install a high-performance spark plug. A high-performance spark plug can help improve the engine's combustion efficiency, which can also lead to more power.
7. Use higher-octane fuel. Higher-octane fuel is less likely to detonate, which can result in more power.
Some of these modifications may require special tools or knowledge, so it is best to consult with a qualified mechanic before attempting any of them.
