How to Install The Top End of a 80cc 66cc 48cc 2-Stroke Bicycle Engine Kit
Convert your bicycle to a motorized bicycle by adding a 2 stroke engine kit to it. The kit fits best on bikes with 25 to 30mm diameter front down tube and 70 degree Vee type frame like a mountain bike but can be installed on larger diameter tube frames with modifications. “Looks Cool” on the older beach cruiser type coaster brake bikes. The motor bolts to the bicycle frame in the center of the frame (additional mounting options available). A second Heavy Duty chain is attached from the motor to the rear wheel via a second sprocket attached to the rear wheel.
Starting:
2 stroke motor kits are started by “bump” starting them. While holding in the clutch, pedal the bike quickly. When you release the clutch after the bike gets to speed, it push starts the motor.
The kit will average around 25-35 M.P.H depending on rider weight and rear sprocket gear ratio.
Gas Mixture
This bike motor kit comes with everything that you'll need except gas and oil since this is a 2 stroke, 2 stroke oil needs to be added to the fuel. Always mix gas in a gas can, not the gas tank. When the engine is new, it would need to be broken in with a richer mixture, after at least 1 tank of gas, then the mix can be “leaned out” (less oil). Never go less than 32:1 ratio (4oz of oil per Gallon).
- New Motor - 16:1 (8 oz of oil per gallon)
- After Broken in - 32:1 (4 oz of oil per gallon)
You will be able to stop or start the engine as you ride. This kit gets maximum fuel efficiency stock at around 100 miles per gallon.
The Motor will require some assembly, the top end of the motor must be installed.
