Frequently Asked Questions

Q: Why should I choose the .039 (0.99mm) jet over other sizes?

A: The .039 jet is specifically sized to provide the optimal fuel-to-air ratio for modified clone engines. If your engine is running lean at wide-open throttle, this size helps deliver the extra fuel needed to maintain power and prevent overheating.

Q: How do I know if my kart engine needs a jet change?

A: You should consider changing your jet if you notice a loss of power at high RPMs, engine hesitation, or if your spark plug shows signs of a "lean" condition (white or light gray electrode). Always perform plug chops to verify your air-fuel mixture after installing a new jet.

Q: Is this jet compatible with all clone engines?

A: This R.L.V. jet is designed for standard clone racing carburetors. While it fits most common clone platforms, always verify your carburetor model and current jetting baseline before installation to ensure it matches your specific engine build.

Q: Can I buy these in bulk?

A: Yes, if you find that the .039 size is your "go-to" for track conditions, we offer a 5-pack version to ensure you always have spares in your toolbox for quick trackside adjustments.
