• Question: How do I start and stop my bike with the Silver Flying Horse 66cc/80cc Bicycle Engine?
  
  
• Answer: The starting and stopping of this two stroke motor kits is this: 
  
  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.

Bicycle Requirements:

This bike engine kit fits most mens 24" and larger bicycles which includes mountain, cruiser, chopper and road bikes with a V-frame and at least a 8.5" height clearance for the engine. Larger frame size requires drilling into bike frame and use of the universal face plate. Large bikes (with larger frames/down tubes) may require the Universal Motor Mount.

Engine Kit Dimensions

80cc engine kit is about 8.5" height 7" length 5" width. Kit fits on standard 25mm to 29mm frame tube. Larger frame size requires drilling into bike frame and use the universal face plate. Ensure proper fit by reviewing the minimum dimensions.

Gas And Oil Mixture For Fuel Ratio: Use of a synthetic 2 stroke oil is recommended. This bicycle motor engine kit is a 2 cycle/2 stroke design, therefore, a gasoline/oil mixture is necessary as follows:

• When New: 16 to 1 (8oz per Gallon)
• After 2 Tanks Of Break In: 32 to 1 (4oz 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.

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