1. Exhaust system: Replacing the stock exhaust system with a high-flow aftermarket exhaust can help improve airflow and increase horsepower. Look for a system that is designed specifically for the FJR 1300 and is made of high-quality materials.
2. Air intake system: Installing a high-flow air intake system can also help improve airflow and increase horsepower. This can be done by replacing the stock air filter with a high-flow air filter, or by installing a ram-air intake system.
3. Fuel injection system: Upgrading the fuel injection system can help improve fuel delivery and increase horsepower. This can be done by installing a fuel injection controller, which can be programmed to deliver more fuel to the engine.
4. Engine modifications: More extensive engine modifications, such as porting and polishing the cylinder head, increasing the compression ratio, or installing a turbocharger or supercharger, can also increase horsepower. However, these modifications are more expensive and complex, and may require specialized knowledge and equipment to perform.
