Recommended Break In Procedures

  1. Add only professional synthetic 2 stroke oil

  2. The ratio of mixing engine oil and gas fuel must be correct
    0-50 miles: 8oz per gallon
    50-100 miles: 6oz per gallon
    ≥100 Miles:  4oz per gallon

    You have to check the color of the electrode of spark plug to make sure the mixture ratio of engine oil and gas fuel are proper. If the electrode has black color, it means there is too much engine oil and you should decrease its mixture ratio. If the electrode has off-white color, it means the engine oil is not sufficient and you should increase its mixture ratio
