    Answer: Yes, Mikuni RS Series Carbs can be used on street bikes, especially those that have been modified for performance.

Use a carburetor cleaner and a soft brush to clean the jets, float bowl, and body. It's crucial to ensure that all passages are free of debris and not clogged. Regular maintenance not only prolongs the life of the carburetors but also ensures consistent performance, especially for performance-oriented applications.
