Gas And Oil Mixture For Fuel Ratio: (Use of a synthetic 2 stroke oil is recommended.)

The bicycle motor engine is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 4 tanks of fuel, the ratio is 16 to 20 parts gasoline to 1 part 2 cycle oil. After the break-in period, the ratio is increased to 20 to 25 parts gasoline to 1 part oil. The engine crankshaft bearings are lubricated from the oil in the gas mix. A rich break in oil mixture ensures bearings will not cease during engine break in period.

Skills & Experience:

The buyer may need some basic hardware skills, tools, and it takes roughly around 2-3 hours to install and to do some adjustments and fine tuning.

Disclaimer: Down through the years China bike engine factories have always advertised their biggest engine as 80cc therefore we have listed them the same way on our website. However, the bore and stroke of an 80cc being 47x38mm only equals 66cc. Therefore there is no such thing as an 80cc bike motor and it truly does not exist and we want to make sure that you are aware of this.
