Fine-tune your top-end performance with Power Jet Circuit Inserts—designed to control high-RPM fueling on Lectron H-SERIES and Legacy carburetors. These inserts allow riders to adjust the amount of fuel delivered at wide-open throttle, giving you more control over throttle response and peak power without affecting low or midrange performance.
Ideal for elevation changes, temperature swings, or custom builds that demand precise fuel delivery at the top end.
