Mikuni J8-6DH02 Jet Needle 6DH2 Carburetor Replacement

The Mikuni J8-6DH02 (also known as 6DH2) is a precision-engineered jet needle designed for Mikuni carburetors. This component plays a critical role in fuel metering, controlling the air-fuel mixture in the mid-range throttle position, specifically from 1/4 to 3/4 throttle opening.

Key Features:

• Direct replacement jet needle for Mikuni carburetors
• Controls fuel mixture during mid-range throttle operation
• Precision-tapered design determines fuel flow rate
• Thinner needle diameter increases fuel draw for richer mixture
• Thicker needle diameter decreases fuel draw for leaner mixture

This jet needle is an essential tuning component for optimizing carburetor performance. The taper profile of the 6DH2 needle directly affects fuel delivery characteristics, allowing you to fine-tune your engine's performance across the mid-range power band. Ideal for rebuilds, performance tuning, or replacing worn needles to restore proper carburetor function.
