Choosing the right camshaft for a Honda Clone engine is no longer just about peak horsepower—it’s about maximizing usable power across the RPM range. As kart racing and recreational engine builds continue to evolve, traditional camshaft designs often fall short in modern combinations with high-flow heads and larger carburetors.

In this guide, we break down the differences between the Reaper, Reaper Jr., and Banzai II camshafts, explain how airflow and engine setup impact cam performance, and show how to improve acceleration, throttle response, and overall average power. Whether you're building for sprint kart racing, minibikes, or high-performance recreational use, this article will help you choose the right camshaft for your setup.
