MIKUNI Genuine Mikuni Jet Needle J8-6FM46

The jet needle is the critical component controlling your carburetor's fuel delivery during mid-range throttle operation—the RPM band where most riding happens. A worn or incorrect jet needle causes hesitation, lean stumbling, or overfueling that robs your engine of responsive performance. The genuine Mikuni J8-6FM46 restores precise fuel metering calibrated by Mikuni's engineers, ensuring smooth power delivery across your entire throttle range.

This is a direct replacement for Mikuni VM carburetors and compatible OE Mikuni units. Installation is straightforward—needle removal and replacement takes minutes without special tools. If you're tuning your carburetor or replacing wear items for consistent performance, this genuine component delivers the accuracy you need.
