Product Details

The Mikuni 019.580 is a Keihin N424-36 series main jet with a #100 orifice size. This precision-manufactured carburetor jet controls fuel flow in the main metering circuit, directly affecting engine performance at mid to full throttle positions.

Key Specifications:

  • Jet size: #100 orifice
  • Type: N424-36 series main jet
  • Compatible with Keihin carburetors using N424-36 series jets
  • Precision-drilled brass construction for accurate fuel metering
  • Direct replacement for OEM Keihin main jets

Main jets are critical tuning components that allow you to optimize air-fuel mixture for your specific application, altitude, and performance modifications. Installing a larger jet number increases fuel flow, while a smaller number reduces fuel flow. Proper jet selection ensures optimal engine performance, throttle response, and fuel economy.

All good!
