Description
This Tokyomods Keihin OBEKR 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 OBEKR. It is not a universal carburetor fitment or a symptom-based upgrade.
Keihin OBEKR needle details
- Needle code: OBEKR
- Carburetor family: compatible 35–41 mm Keihin FCR/FCR-MX carburetors using this needle format
- Package: one jet needle and one retaining clip; this is not a complete jet kit
Documented rider and tuner context
Documented factory-baseline references include the 2002 Honda CRF450R, the 2004 Yamaha YZ250F, and the US-spec 2000 Yamaha YZ426F (5JG1). OBEKR also appears as an optional tuning needle for selected KX250F, RM-Z250, KTM, and Husaberg FCR/FCR-MX applications. A catalog listing confirms documented use, not correct calibration for every vehicle.
Pro Circuit also documented OBEKR in complete 2004 KX250F and RM-Z250 setups under stated fuel, altitude, and temperature conditions. Rider reports around early four-strokes and FCR39/FCR41 conversions vary, so experienced customers order OBEKR only when the exact code is part of a known combination.
Before you order
Match the full OBEKR 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 OBEKR jet needle and one retaining clip.
Will OBEKR fit every FCR or FCR-MX carburetor?
No. The carburetor family may be compatible while OBEKR 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 OBEKR before purchase.

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