Description
This Tokyomods Keihin NCVS 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 NCVS. It is not a universal carburetor fitment or a symptom-based upgrade.

Documented rider and tuner context
NCVS appears in Honda optional-needle tables, as an optional profile for selected Kawasaki KX450F applications, and in rider discussions around modified or uncorked CRF450X setups. Those recommendations are combination-specific. Treat them as evidence of established use, not as blanket model fitment or a promise that NCVS is right for every machine.
Within the closely related NCVR/NCVS comparison, NCVS has the larger published straight diameter (2.765 mm versus 2.755 mm). All else equal, it is relatively leaner in the straight-diameter transition range; taper, clip, jets, and the rest of the setup still matter.
Before you order
Match the full NCVS 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 NCVS jet needle and one retaining clip.
Will NCVS fit every FCR or FCR-MX carburetor?
No. The carburetor family may be compatible while NCVS 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 NCVS before purchase.

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