An actual 70cc kit! (not 66cc)

Despite what it says, I still believe that its the standard chinese engine. It says one piece head/cylinder. When you enlarge the pic of it you can clearly se that it is the regular 2 piece setup. All I can see that they 'claim' is different is the stroke distance. The thing about these engines is that most people do not check to make sure the specs on the website are the same as on the engine they recieve (as far as bore, stroke, cc, etc). The people on this forum most likely do, but the average crowd does not, which allows them to make claims that most people do not take the time to prove false.

^^^ Is all my opinion.

all the motors from china lie.. they dont test them to see output.. so a 66.6 cc could be 50 cc.. you cant trust anything from china there is no stadard or quality control..
