Al, I seem to remember the first several generations of GO motors (post 2005) to be called GO-Tech and I am pretty sure that is the name Race Factor used for the manufacturer here in the states I am not sure if it was just a name mix up or what on his part. In all reality does it even matter? The reason GO had a bad name in the states was due to issues with the distributor (Race Factor) and some flaws with material strength. Oh and lets not forget the carb issues. I had my fair share of issues with all of them. All of which have since been fixed in a major way. Now then I have been doing some research over the last few months on the GO factory and have come to realize they do in fact produce motor parts for several other motor companies. Does that make them GO motors? No it does not. Those motors are built to that company's specs in the same factory that builds GO motors. Some things will be the same on all of those motors because it is very expensive to develop produce molds for the harder metals. That is why if you look at most of the Taiwan motors things like rods will be same through all of those lines. Cast molds on the other hand are cheap to produce hence the fact that most the heads and cases are different. The main differences will be timing on the sleeve. Anyway enough ranting. Your Preciprocate motor is built in the same factory that makes the GO GX line of engines and the previous Pro Series of motors and shares some parts from each of those lines. Most importantly it has the same carb and rod seen in the GX line. It has the uncoated crank from the Pro Series line, the same molded case from both lines and the head design shared by the JS line. Somebody correct me if im wrong but I am pretty sure im not.
