Jet Mikuni Pilot #50 (4/Pkt)

The Mikuni Pilot Jet #50 is a genuine replacement slow jet for Mikuni slide and CV carburettors. Pilot jets govern fuel delivery at idle and low throttle openings, making them a critical tuning and maintenance component for correct carburetion.

Sold as a pack of four, this kit suits riders undertaking a full jetting service, building multiple carbs, or stocking a workshop supply. The #50 size is a common pilot jet specification across a wide range of Mikuni-carburetted motorcycles, ATVs and powersport equipment.

Never use wire, drill bits or abrasives to clear the orifice — this permanently alters the jet size and will cause incorrect fuelling.
Clean with aerosol carburetor cleaner and blow out with compressed air only.
Inspect the orifice and threads for wear, corrosion or damage before installation; replace if in doubt.
Ensure the jet is seated firmly and correctly torqued — over-tightening can strip the brass thread or carb body.
Verify the #50 size matches your engine's jetting requirements before fitting; consult a jetting chart or tuning guide for your specific carburettor model and application.
When tuning for altitude or temperature changes, adjust pilot jet size in single increments and test ride between changes.
Store spare jets in a sealed container away from moisture and solvents to prevent corrosion of the brass orifice.
