How do I de-restrict my 1991 Suzuki TS125R?

To de-restrict your 1991 Suzuki TS125R, you can start by removing any factory-installed restrictions such as the exhaust baffle or restrictor plate, which may limit airflow and power. Additionally, check the carburetor for any limiting jets and consider upgrading to a performance carburetor for better fuel delivery. You may also want to adjust the gearing for improved acceleration and top speed. Always ensure that any modifications comply with local regulations and safety standards.
