They are made by LINHAI in china and was told by an authorized Coleman warranty dealer they are a knock off of a Yamaha ATV.

The Chinese manufacturers typically claim that their engine is a copy of (insert real maker here). The trouble is they don't use the same materials, don't machine to the same tolerances and don't have the quality control of the major brands.
