I'm new to the whole clone thing. I understand the Chinese basically stole Honda's design for the 5.5 and 6.5 engines. I think Honda has even tried to sue, though unsuccessfully. I also see that both engines are sold under at least a half dozen names. Lifan, Greyhound from Harbor Freight, “Iron Horse” from Northern, Jiangdong, Champion, etc. Are these different “brands” all the same? Are they all from one manufacturer or different? Are all the parts interchangeable among the various clones and Hondas? It sounds like they are. I’m curious. I just bought a Mini Baja with the Jiangdong 5.5 that’s not running. It’ll fire on starting fluid, so I’m pretty sure the carb needs a good cleaning. I’m also thinking of building a Serengeti Puma kit with my son and will likely put a clone on it. So, are they all the same?
