E-Z-GO Freedom RXV Carburetor Jet Size

On FJ400D-equipped carbureted E-Z-GO Freedom RXV models, the documented factory carburetor uses a #106 main jet and #52 pilot jet. Confirm the engine before ordering, because earlier carbureted versions can use different jetting and later EFI versions have no carburetor jets.

Before ordering

Identify the engine and carburetor, then read the number stamped on the existing brass jet.

Lean symptoms

Needing choke, surging or load bog can also come from a clogged passage, weak fuel supply or intake leak.

Rich symptoms

Black smoke or plug fouling can also come from a stuck choke, high float level or leaking needle valve.

How to choose the correct E-Z-GO Freedom RXV jet

Confirm that this E-Z-GO Freedom RXV matches the FJ400D-equipped carbureted gasoline version described here. Later EFI versions do not use carburetor jets.

Engine/application: 401 cc Kawasaki FJ400D on documented carbureted years. Carburetor: Kawasaki fixed-float-bowl carburetor.

Remove the bowl and jets only after cleaning the carburetor exterior. Read the stamped jet number; do not estimate jet size from hole diameter or appearance.

Main jet: #106 on documented FJ400D carbureted applications. Altitude guidance: Use the exact model-year parts manual for altitude-specific jetting.

Pilot jet: #52 on documented FJ400D carbureted applications. If it only runs with choke or will not idle, clean the pilot circuit and check for an intake leak before changing the jet size.

After fitting the correct jets, verify warm idle, clean takeoff and full-load response. If the problem remains, check fuel level, float, needle valve, choke and fuel-pump delivery before changing jet size again.

Freedom RXV jetting symptoms

Needs choke to run

Clean the pilot and main circuits and check fuel supply and an intake leak before fitting a larger jet.

Bogs under load

A restricted main jet can cause this, but so can weak pump flow, low bowl fuel level or a blocked filter.

Black smoke / fouled plug

Check choke position, float level and needle sealing before assuming the main jet is too large.

Runs well only at low speed

Main-jet or main-nozzle restriction becomes more likely once the pilot circuit is known to be clear.

Poor idle only

The pilot circuit matters much more than the main jet at idle.

High-altitude operation

Use the model-specific elevation chart where available; do not guess how many jet sizes to reduce.

E-Z-GO Freedom RXV carburetor jet FAQ

What is the E-Z-GO Freedom RXV main jet size?

#106 on documented FJ400D carbureted applications. The documented 401 cc FJ400D carburetor uses a #106 main jet and #52 pilot jet. Confirm the engine and model year before ordering.

What is the E-Z-GO Freedom RXV pilot jet size?

#52 on documented FJ400D carbureted applications.

Does altitude change the E-Z-GO Freedom RXV main jet?

Use the exact model-year parts manual for altitude-specific jetting.

Can I install a larger jet in an E-Z-GO Freedom RXV?

Only after confirming the engine, carburetor, altitude and cause of the lean symptom. A clogged passage, intake leak or weak fuel supply should not be corrected with an oversized jet.

How do I identify the correct E-Z-GO Freedom RXV carburetor jet?

Use the stamped jet number together with the engine code, carburetor ID and model year. Cross-check those identifiers against the matching factory parts or service information.

What is the difference between the main and pilot jet on an E-Z-GO Freedom RXV?

The pilot circuit controls idle and very low-throttle fueling. The main jet becomes dominant as airflow, throttle opening and engine load increase.

Verify the jet before ordering

Jet sizes can change with engine, carburetor revision, model year and altitude. This page applies only to the FJ400D-equipped carbureted gasoline version. Do not drill jets or assume a jet from another model is equivalent. Confirm the engine, carburetor ID and existing jet markings for your exact E-Z-GO Freedom RXV.
