The motor is like the thatsdax motor (same head and large cylinder studs). I was told it was a 60cc, but after taking the head off, it had a 47mm bore and 40mm stroke, which means its an 80cc (70cc). It came with a chrome tank, new style muffler, new style air cleaner, old style clutch lever, and old style chain guide.
The overall quality of the kit looks very good. Use the email address on the urbanengines.com Web site to get a price quote from Manny.
