Product Details

The Mikuni 4/042-290 is a precision-engineered main jet designed for optimal fuel metering in Mikuni carburetor systems. This large hex type main jet is a direct replacement component that controls the fuel flow through the main fuel circuit of the carburetor, playing a critical role in engine performance and fuel mixture calibration.

Key Features:

  • Large hex design for easy installation and removal with standard tools
  • Compatible with most Mikuni carburetor models
  • Precision-machined orifice for accurate fuel metering
  • Mikuni part number 4/042 series - genuine OEM quality
  • Allows for fine-tuning of air/fuel mixture for optimal performance

Main jets are essential tuning components that determine the fuel delivery at mid to full throttle positions. Changing jet sizes allows you to compensate for altitude changes, performance modifications, or temperature variations. The large hex design provides a secure grip for installation without damaging the jet body.
