Product Details

The Mikuni 4/042-90 is a precision main jet designed for use in most Mikuni carburetors. This large hex-type jet features the traditional hex head design that allows for easy installation and removal with standard tools.

Key Features:

  • Large hex head design for easy installation
  • Mikuni part number 4/042 series
  • Jet size: 90
  • Compatible with most Mikuni carburetor models
  • Precision-drilled brass construction for accurate fuel metering

Main jets are critical components in carburetor tuning, controlling the fuel flow at wide-open throttle and high RPM ranges. The jet size number (90) indicates the orifice diameter, allowing you to fine-tune your air/fuel mixture for optimal performance. Whether you're compensating for altitude changes, engine modifications, or simply maintaining your carburetor, having the correct main jet size ensures proper fuel delivery and engine performance.

Being able to use Amazon as a payment is convenient. It is also helpful that you show the item is in stock.
