Customer and tuner recommendation context
Honda documented NCYR as the standard profile for the 2004 CRF250R, and period rider/tuner recommendations also identify NCYR in 2004 CRF250R jetting combinations. Other model years used different factory needles, so TokyoMods treats NCYR as its selected tuning profile for the full listed range rather than an original-equipment claim for every year.
Before you order
Confirm the full NCYR marking or a known TokyoMods or trusted-tuner specification. Complete calibration depends on the engine, carburetor, fuel, intake and exhaust, altitude, temperature, jets, accelerator-pump setup, and clip position. No universal clip position or jetting recipe is supplied. Use period customer jetting examples only as context; their fuel, altitude, engine, exhaust, and other carburetor settings may differ from yours.
