Product Details

The Mikuni J8-6EJ12-59 is a precision-engineered jet needle designed specifically for TMX38 flat slide carburetors. This replacement jet needle plays a critical role in fuel metering, controlling fuel flow through the needle jet to regulate the air-fuel mixture in the mid-throttle range.

Key Features:

  • Direct replacement jet needle for Mikuni TMX38 flat slide carburetors
  • Part number J8-6EJ12-59 for accurate identification and ordering
  • Precision-machined taper ensures accurate fuel metering
  • Controls mid-range throttle performance and fuel delivery
  • Genuine Mikuni OEM component for reliable fitment

The jet needle works in conjunction with the needle jet to meter fuel as the throttle slide opens, making it essential for proper carburetor tuning and engine performance. Replacing worn or incorrect jet needles can restore optimal throttle response and fuel efficiency.

I ordered street performance brake pads. Autoplicity had the best price on the net and were shipped quick. Can't wait to get them installed.

Found the best prices here and the shipping was extremely fast. Happy with my choice to shop here.

Very fast service

Will do so later

have to go back and look but i thought it was free shipping

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.
