What the number itself says

Reading LJASX.120GKG left to right: L is the model-year letter for 2020, JAS is the three-character code the EPA assigned to Jass Motorsports as certificate holder, X marks an off-road certification, .120 is the displacement in litres, so 120cc and GKG is Jass Motorsports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Jass Motorsports submitted for this family (model KD-125FM5) carried engine code 152FMI. In the Chinese engine-model convention that reads as one cylinder with a nominal 52 mm bore, FMI series.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor. There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 5.8 kW (about 8 hp) at 7,500 rpm, driving through a 3-speed automatic.

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
