Product Details

The Mikuni 4/042-170 is a precision-machined main jet designed for optimal fuel metering in Mikuni carburetors. This large hex type jet features a #170 orifice size, controlling the primary fuel flow at mid to full throttle operation.

Key Features:

  • Large hex head design for easy installation and removal with standard tools
  • #170 jet size for precise fuel metering calibration
  • Compatible with most Mikuni carburetor models including VM, TM, and HSR series
  • Manufactured to OEM specifications for consistent flow characteristics
  • Brass construction ensures durability and resistance to fuel corrosion

Main jets are critical tuning components that allow you to adjust air/fuel mixture for performance optimization based on altitude, temperature, and engine modifications. The large hex design is the most common Mikuni jet style, found in applications ranging from motorcycles and ATVs to snowmobiles and personal watercraft.
