Alright, I got the other numbers from the guy and it is a 150, the other numbers are HL157QMJ. is this a GY6 and what defines an engine as a GY6?

[sprocket]

Yes it is a GY6...HL means it is made by Hanglong a division of Zhejiang Hongzhou Motorcycle Co

Many Chinese scooter use the GY6 design engine but there are many manufacturers, everyone copies from everyone else. It is an engine from the early 1980s that is based on a Honda horizontal engine, however Honda never made the GY6.

The GY6 comes in a number of bore sizes from 50cc to 250cc and has a number of variations but probably 90% of 12-13" wheel, 150cc engines are a standard GY6 longcase. 16 " wheel scooters use a GY6-B engine and they have many differences internally.

Is there any article that describes the specific differences between a GY6 and a GY6-B? My 16" tire Znen Flyscooter uses the 16" tires and I believe that it has that special engine...buying correct parts is a crapshoot.

You can see the difference here. Note the width and the extra gear box on the B engine
