Product Details

The Mikuni 4/042-190 is a precision-engineered main jet designed for optimal fuel metering in Mikuni carburetors. This large hex-style jet is one of the most commonly used components across Mikuni's carburetor lineup, providing accurate fuel delivery for consistent 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 BSR series
  • Precision-manufactured brass construction for accurate fuel flow
  • Mikuni part number series 4/042 for reliable OEM replacement
  • Calibrated jet orifice ensures proper air-fuel mixture at wide-open throttle

Main jets are critical tuning components that control fuel flow at higher throttle positions. Changing jet sizes allows you to fine-tune your carburetor for different altitudes, temperatures, or engine modifications. The large hex design provides a secure grip for installation and prevents rounding of the hex during removal.

Website was easy and great to use. Received products and they were exactly what I was looking for! This saved me so much money doing the install myself and better parts than any auto shop out there. Thanks!

Bought a Husky gearbox for my Silverado, great price and a great product. Install was simple and the fit was perfect. Gone are the days of opening the rear door and all the items under the seat sliding out. Great for my hitch, tow straps, jumper cables and other miscellaneous must haves in a truck. Great seller the price was the best on the net even with shipping. Item arrived quick and in perfect shape. Thanks!!
