What the number itself says
Reading 9CGQX.049DB1 left to right: 9 is the model-year letter for 2009, CGQ is the three-character code the EPA assigned to Hensim USA as certificate holder, X marks an off-road certification, .049 is the displacement in litres, so 49cc and DB1 is Hensim USA's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
