What the number itself says
Reading ESHKX.086ATA left to right: E is the model-year letter for 2014, SHK is the three-character code the EPA assigned to Shenke Usa as certificate holder, X marks an off-road certification, .086 is the displacement in litres, so 86cc and ATA is Shenke Usa's 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
