Description

Precise fuel metering is fundamental to carburetor tuning, and the right main jet directly impacts throttle response, fuel economy, and engine performance across the RPM band. Whether you're fine-tuning a Mikuni VM or TMX series carburetor for track conditions or dialing in a street setup, the #190 main jet gives you the exact atomization your engine demands. This 4-pack ensures you have spares on hand for testing different jetting configurations without downtime.

JJ-Motorsports sources genuine Mikuni jets manufactured to OEM specifications in Japan, guaranteeing dimensional accuracy and reliable fuel flow rates that budget alternatives simply cannot match.
