Recommended Break In Procedures
Add only professional synthetic 2 stroke oil
The ratio of mixing engine oil and gas fuel must be correct
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.
Break-in period is 500km or approximately 315 miles.
Take it slow to start! You don’t want to ruin your brand-new engine! While in the break in period NEVER go over ½ throttle.
Give it a break… In order to avoid over-heating don’t run for more than 30 minutes at a time and allow the engine time to cool off before starting up again.
