What the number itself says
Reading BPCGC.049S4A left to right: B is the model-year letter for 2011, PCG is the three-character code the EPA assigned to Peace Industry Group (Usa) as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and S4A is Peace Industry Group (Usa)'s own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
