Description
This Tokyomods Keihin NCVR jet needle includes the retaining clip and is intended for a compatible FCR/FCR-MX carburetor whose existing calibration or trusted tuning specification calls for NCVR. It is not a universal carburetor fitment or a symptom-based upgrade.

Documented rider and tuner context
NCVR is documented as the standard needle on selected 2006-2008 Kawasaki KX450F applications and appears in Honda optional-needle tables. Riders comparing adjacent Keihin profiles often consider NCVR only after a known tuner or manual specification points to it. Model, market, and complete carburetor setup still determine whether the code is appropriate.
Within the closely related NCVR/NCVS comparison, NCVR has the smaller published straight diameter (2.755 mm versus 2.765 mm). All else equal, it is relatively richer in the straight-diameter transition range; that is not an across-the-range claim or a universal recommendation.
Before you order
Match the full NCVR marking on the needle being replaced or follow a known TokyoMods, service-manual, or trusted-tuner specification. Correct calibration depends on the entire combination, including the engine, carburetor, fuel, intake and exhaust, altitude, temperature, jets, accelerator-pump setup, and clip position. No universal clip or jetting setting is supplied.
Frequently asked questions
What is included?
One Tokyomods Keihin NCVR jet needle and one retaining clip.
Will NCVR fit every FCR or FCR-MX carburetor?
No. The carburetor family may be compatible while NCVR is still the wrong calibration. Verify the exact needle format and code for your setup.
What clip position should I use?
Use the setting from the established tune you are following. TokyoMods does not present one clip position as correct for every motorcycle or riding condition.
Is this needle returnable?
No. Verify NCVR before purchase.

Final sale: Carburetor needles are precision tuning components and are not returnable. Confirm the stamped needle code and intended specification before ordering.
