here's a how to;;;
When ordering parts for your scooter it is important to have the engine number that you can find at the bottom of the transmission case. There are variations but this pictured code would translate as follows: first number is always a "1" meaning one cylinder. The next two, in this instance "57" is the bore of the motor in millimeters. The "Q" means a GY6 motor. The last two letters denote the size of the engine, MJ being a 150cc.
there are a couple of variations of the gy6 so thats why you
have to know which motor you have.
