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.
