In this episode of Navigating Amateur Motocross, Coach Robb and Derek Harris of HP Development break down why riders often believe their bike, or their body, “isn’t fast enough,” even when the data (like dyno results) shows the setup is strong. Derek explains that most performance complaints don’t require a full rebuild; they usually come down to optimizing within a small “window” using jetting, needle clip position, power valve adjustment, reeds, hour meter tracking, and detailed notes. Those tiny 1–3% tweaks may not show clearly on a dyno, but they can feel huge on track especially for riders chasing sharper response and better late-race pull.
