Product Details

The Mikuni 4/042-440 is a precision-machined main jet designed for use in a wide range of Mikuni carburetors. This large hex-style jet features the traditional six-sided head design that makes installation and removal simple with standard tools.

Key Features:

  • Large hex head design for easy installation and adjustment
  • Precision-drilled orifice for accurate fuel metering
  • Compatible with most Mikuni carburetor models including VM, TM, and TMX series
  • Mikuni part number series 4/042 for guaranteed OEM quality
