Mikuni M28100145 VM28/1001 Pilot Jet Size #45 - 4-Pack

The Mikuni M28/1001 Series Pilot Jet #45 is a genuine OEM-quality brass pilot jet designed for precise fuel metering at low throttle openings. Sold as a convenient 4-pack, these jets are an essential tuning and replacement component for a wide range of Mikuni carburetors used in powersports applications including OEM and Banshee carburetor configurations.

Pilot jets govern the fuel delivery in the idle and low-speed circuit of the carburetor. Selecting the correct jet size is critical — a jet that is too large will result in an overly rich air/fuel mixture, while a jet that is too small will cause a lean condition. The M28/1001 series is available in increments of 2.5, ranging from size 15 to 70, allowing for precise tuning adjustments.
