Product Details

The Mikuni 4/042-100 is a size 100 main jet featuring the large hex design used in most Mikuni carburetors. This precision-manufactured jet controls fuel flow through the main fuel circuit, allowing you to fine-tune your carburetor's air-fuel mixture for optimal engine performance.

Key Features:

  • Size 100 main jet for precise fuel metering
  • Large hex head design for easy installation and removal
  • Compatible with most Mikuni carburetors including VM, TM, and BSR series
  • Mikuni OEM quality construction ensures consistent flow characteristics
  • Individual part number 134-8100

Main jets are essential tuning components that determine fuel delivery at mid to full throttle positions. Changing jet sizes allows you to compensate for altitude changes, engine modifications, or exhaust system upgrades. This large hex style features a larger hex head compared to standard round-top jets, making it easier to service with common tools.

Great thanks !!!

Good

Very nice.

Thanks

Never received confirmation of product being shipped and was unable to get information from the web site. Had to call customer service (slow) where I finally got a tracking number. Other than that, good experience.

Easy order process.

Fast and quick.

Easy shopping, good prices. Would like just a little more specific information on the item descriptions.

After weeks of shopping around, I was able to find the best price from Autoplicity. The ordering process was very simple since I had the option to pay through my Amazon account. Great experience.

Easy and quick. Great price, too!
