2024–2026 YZ250F Second Injector Kit

The JPM Second Injector Kit is the essential performance upgrade for the latest 2024–2026 YZ250F—engineered to deliver instant horsepower and torque gains across the entire RPM range. From explosive low-end drive to top-end overrev, the improvement is undeniable—whether you’re on a stock YZ or a fully tuned race bike.

Paired with the JPM-Tuned Vortex ECU, this package unleashes 10 exclusive JPM maps, each developed through real-world testing with top-level riders to suit a variety of tracks, fuels, and weather conditions. Fine-tuning your setup is quick and effortless—just a flat-head screwdriver and you’re race-ready.

Unlike other kits that rely on fragile plastic fittings, JPM’s twin-outlet fuel feed design ensures maximum reliability and consistent fuel delivery under the toughest race conditions. Installation is simple, clean, and 100% reversible, allowing you to return your bike to stock whenever needed.
