The engine is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 2 gallons of fuel), Break in ratio for 80cc is 20 to 1, 8 oz per Gallon. After the break-in period, the ratio is increased to 30 to 35 parts gasoline to 1 part oil.  4 to 6 oz. per Gal. depending on use. Before riding and on a periodic basis continually check Nuts and Bolts for tightness. Engine vibration can loosen. ?LockTight? is recommended.
