Product Details

The Mikuni 4/042-125 is a precision brass main jet designed for use in most Mikuni carburetors. This large hex style metering jet controls fuel flow through the carburetor's main circuit, allowing you to fine-tune air/fuel mixture for optimal engine performance.

Key Features:

  • Large hex head design for easy installation and removal
  • Precision-drilled brass construction for accurate fuel metering
  • 125 jet size for specific fuel flow requirements
  • Compatible with most Mikuni carburetor models
  • OEM Mikuni quality and specifications

Main jets are essential tuning components that allow you to adjust carburetor performance based on altitude, temperature, engine modifications, and riding conditions. The large hex design provides a secure grip for jet changes during carburetor tuning and maintenance.

Fast and efficient. Thank you!

i like the pcice

Very pleased and will be back for my automotive parts

They had what I wanted at a price that I was willing to pay for.

Allways been easy to order, quick shipping also.

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!

Easy
