You can still pedal bike like normal with clutch lever held in or locked in with button.

To Start: It's just like riding a bike normally, hold in the clutch and pedal the bike to get some speed, then release the clutch to "Jump Start" the motor. If you know of or remember jump starting a Manual VW Bug this start method is the same.

To Stop: While the engine is running you can hold in the clutch and the engine will idle. Push the Kill Switch on the throttle to kill the motor. The clutch must be held in when the bike is in motion or the motor will keep running.

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

• When New: 16 to 1 (8oz per Gallon)

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.

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 exists and we want to make sure that you are aware of this.
