Be assured the mixing ratio for fuel and oil:16:1 for break period (first 300 miles) / 20:1 after(18:1 is much better in summer because of the hot weather);air cylinder might take some time to adjust to the load. Thus to avoid possible complications for the motor, please limit the riding time to a maximum of 1 hour for the first few rides.

Description
Important notes must read before starting the engine.
When the engine starts fresh, you need to be careful during the break-in period or the engine will break or seize due to improper use.
For the first two tanks, use oil mixture 16 : 1 which is about 8oz of oil per gallon of gasoline, don't go over 20 miles per hour and keep your rides in less than 20 minutes to let the engine cool down. When your engine is cool enough not burning your hand usually about 30 minutes, that's when you can ride again.
For the second two tanks, use oil mixture ratio 6oz of oil per gallon of gasoline, follow the same guideline above when riding.
After 4 tanks, use oil mixture ration 4oz of oil per gallon of gasoline forever, DON'T go below of this ratio.
Above steps to ensure a long life engine for longer rides. Please note, the motor is NOT designed for racing, if you keep the throttle wide open at all time, eventually you will blow up the motor.
