Product Details

The Mikuni N102.221-45 is a precision-machined main jet designed for optimal fuel metering in high-performance carburetors. This #45 size small round main jet is a critical tuning component that controls fuel flow through the main fuel circuit, allowing you to fine-tune air-fuel ratios for maximum performance and efficiency.

Key Features:

  • Main jet size: #45 (0.45mm orifice)
  • Small round style design for precise fuel metering
  • Precision-manufactured brass construction for consistent flow characteristics
  • Direct replacement for worn or damaged jets
  • Essential component for carburetor tuning and rejetting

Compatibility:

  • Fits Mikuni SBN 38 carburetors
  • Fits Mikuni SBN 44 carburetors
  • Fits Mikuni SBN 46 carburetors

Mikuni main jets are numbered according to their orifice size, with the #45 designation indicating a 0.45mm opening. Changing jet sizes allows tuners to compensate for altitude changes, exhaust modifications, air filter upgrades, and other performance modifications that affect air-fuel mixture requirements.
