Product Details

The Mikuni 4/042-120 is a large hex-style main jet designed for precise fuel metering in Mikuni carburetors. This jet controls the fuel flow at higher throttle openings, making it a critical component for carburetor tuning and optimal engine performance.

Key Features:

  • Large hex design for easy installation and removal with standard tools
  • Compatible with most Mikuni carburetor models including VM, TM, and BS series
  • Precision-manufactured brass construction for accurate fuel metering
  • Essential component for carburetor jetting and performance tuning

Main jets are consumable tuning components that allow riders and mechanics to optimize air-fuel ratios for different altitudes, temperatures, and performance modifications. The large hex design provides superior grip and reduces the risk of stripping compared to smaller slot-style jets.
