Note: This system of adjusters is common to motorcycles and BMX bicycles. If you are not familiar with it or do not feel comfortable performing the ad- justment, consult an authorized Razor service center or a quali- fied BMX bike or motorcycle mechanic.

The chain should be “just taut”

–in other words snug, but not piano-wire tight. The tension should be similar to the fan chain on an automobile. BE CAREFUL NOT TO ADJUST TOO TIGHT. The tensioning system can easily impart too much ten- sion and snap the chain or bend the motor shaft. Adjust 1/8 to 1/4 turn at a time and check the tension each time.
