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.
