Precision-machined from high-quality brass, this jet offers excellent resistance to fuel additives and corrosion. Replacing a clogged or worn idle jet is essential for solving starting issues, erratic idling, or "bogging" when first opening the throttle. Using genuine Keihin components ensures that your jetting remains consistent with factory specifications for optimal engine health.

Installation involves removing the carburetor bowl to access the jet block. It is recommended to clean the entire carburetor circuit when replacing jets to prevent debris from immediately clogging the new part. Always verify your specific tuning requirements, as altitude and temperature may necessitate different jet sizes.
