Frequently Asked Questions
A bleed pilot jet controls the amount of fuel delivered at idle and low throttle positions. The bleed hole allows air to mix with fuel, affecting the fuel-air ratio for smooth idle and low-speed operation.
Check your carburetor's original jet size (usually stamped on the jet itself) or consult your vehicle's service manual. Pilot jet sizes typically range from 17.5 to 25, with larger numbers providing richer mixtures.
On some carburetors, pilot jets can be accessed without full removal, but complete carburetor removal is often recommended for proper cleaning and inspection.
Rough idle, hesitation at low throttle, difficulty starting, or poor low-speed response may indicate incorrect pilot jet sizing.
Not all Mikuni jets are interchangeable. Verify your specific carburetor model and jet specifications before purchasing, as different carburetors may have different jet seat designs.
