What does an advanced timing curve do?

An advanced timing curve changes when the spark plug fires in relation to the piston's position. This can lead to improved throttle response and a more efficient burn, potentially increasing overall engine performance.

Is this a difficult part to install?

No, this Rev Box is designed as a direct plug-in replacement for your stock CDI box. This means it should connect directly to your ATV's existing wiring harness without requiring complex modifications.

What is the warranty on this Rev Box?

The Big Gun Rev Box comes with a 6-month limited warranty from the manufacturer. This covers defects in materials and workmanship during that period.
