For Goped scooters – Fits in G23LH and G43L (GSR40) engines.

NOT for use in R/C style engines (Zenoah G230RC / G240RC / G260RC / G270RC / G290RC / G320RC / CY23RC / CY26RC / CY27RC / F270 / CY29RC / GP290 etc) – the timing is already advanced on these engines, installing a rockit key will over advance the timing and hurt your engine's performance, and potentially damage the engine as well.
