Frequently Asked Questions
The main jet controls the fuel/air mixture at mid-to-high throttle positions. A larger number (like 180) means more fuel flow. Choosing the correct size depends on altitude, temperature, and engine modifications.
You need to know your carburetor model and current jetting setup. The 180 is a mid-range size. Consult your carburetor manual, manufacturer recommendations, or tuning guides for your specific application.
No. Mikuni makes different carburetor models with different jet port sizes. Verify your carburetor model (e.g., VM26, TM33, etc.) before purchasing. The 'large round' designation helps, but confirmation is essential.
The main jet controls fuel at mid-to-high throttle, while the pilot jet controls fuel at idle and low throttle. Both may need adjustment for proper tuning.
Main jets don't typically wear out. You change them for tuning purposes (altitude changes, engine modifications, performance adjustments). They can last indefinitely if not damaged.
