There's a metal plate on the scooter somewhere that has the factory name that assembled the scooter. The engine may or may not have been made at the point of assembly. It's the same as a Flyscooter Cadenza or a Znen (Lance) Phoenix. The engine is different that a normal Chinese 150cc engine. It's a 157QMJ-3. It takes a 906mm drive belt. The cylinder and cylinder head are different that a standard 157QMJ. The head is taller and the bolt holes are differently spaced. The valves are 80mm instead of 60mm long. I had one in the shop before. It had a burnt valve. I had to go through a third party to get a new one and a head gasket from Lance cause Lance requires you have a commercial account with them.
I used this site for the parts. They were called Bandit now they are Viper. They ordered the pats from Lance and Lance shipped them directly to me since Lance headquarters is close to my place here in So. Cal. I called them on the phone to place the order with a Visa card number.
