Hey guys. I just fired my chinese 70cc up tonight. I'm really happy with how it went together and everything was ready to go out of the box, like the carb and throttle assembly. Though I didn't file the drive sprocket through lack of a decent file and desire to take it out to get at it properly. It's dark and wet out so I didn't do anything rash. Was pleased how it started, but it did bog down considerably. I'm about 260 pounds so it has a load to push. How can I postively ID the engine as a 70cc?:???: Z-Box Engines here in Australia does give bore and stroke details for both sizes. The 70cc bore is 47mm and the 48 is 40mm. Stroke is the same. But I doubt I'll be taking the head off to check. lol First one I've ever ridden so I can't compare to a 48cc.
