Mikuni N102.221-220 Main Carburetor Jet - 220

The Mikuni N102.221-220 is a precision-manufactured main jet designed for Mikuni carburetors. This jet features a #220 orifice size, which controls the amount of fuel flowing through the main fuel circuit during mid to wide-open throttle operation.

Key Features:

• Main jet size: #220 (2.20mm orifice diameter)
• Precision-drilled brass construction for consistent fuel metering
• Direct replacement for OEM Mikuni main jets
• Essential component for carburetor tuning and performance optimization
• Compatible with various Mikuni round-slide and flat-slide carburetors

Main jets are critical tuning components that allow you to adjust air-fuel ratios for optimal engine performance across different altitudes, temperatures, and modifications. Larger jet numbers indicate richer fuel delivery, while smaller numbers provide leaner mixtures. The #220 size is commonly used in applications requiring moderate to rich fuel delivery in the main circuit.
