Mikuni Carburetor Pilot Jet for Yamaha TMX BDST

The Mikuni pilot jet (also called a slow jet or idle jet) is a carburetor metering jet. It is the N224.103 series, an OEM-style part for Yamaha Y2, TMX and BDST carburetors, and it also suits BSR-style Rhino carburetors. The pilot jet meters fuel in the idle and low-throttle range, so it directly affects idle quality, off-idle response and low-speed fueling.

Key Features:

• Genuine Mikuni pilot jet from the N224.103 series
• Made in Japan
• Metered fuel passages for accurate idle and low-speed mixture control
• Compact threaded brass-style body that screws into the carburetor
• Available in multiple jet sizes so you can tune the mixture for your setup

Replace a worn, damaged or clogged pilot jet to restore crisp idle and smooth throttle pickup. Swap to a different jet size to fine-tune low-speed fueling after engine, intake or exhaust changes, or when you change altitude or temperature. Choose the size that matches your tuning needs from the available options.
