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

Documented rider and tuner context
OBELP is documented in early Yamaha four-stroke carburetor specifications, including selected 2001 and 2003 YZ250F applications, with year- and market-specific variations. It also appears in WR250F and Yamaha optional-needle references. Riders commonly select it to reproduce a known manual or tuner specification, not simply because a motorcycle uses an FCR-MX carburetor.
Published tuning charts also show OBELP inside complete, condition-specific jetting combinations. Those examples are useful confirmation that the code is established, but they are not universal setup instructions.
Before you order
Match the full OBELP 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 OBELP jet needle and one retaining clip.
Will OBELP fit every FCR or FCR-MX carburetor?
No. The carburetor family may be compatible while OBELP 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 OBELP before purchase.
