Description

Proper jetting is the foundation of carburetor tuning—get it wrong and you're leaving power on the table or risking lean-condition damage. The MIKUNI Main Jet #380 is a direct fit for VM-series carburetors and TMX applications, allowing you to dial in the precise fuel delivery your engine demands across the RPM range. This 4-pack gives you spares on hand so you can experiment with different needle positions and air density conditions without downtime.

Whether you're fine-tuning a street bike, prepping for track day, or building a high-altitude engine, these OEM-quality jets maintain the exacting tolerances MIKUNI is known for—no drift in fuel metering, no clogging issues from poor manufacturing.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
