CHAIN ADjUSTMENT
The chain can stretch during use or may occasionally come out of adjust-
ment. Regular attention to proper chain tension and lubrication will minimize
the risk of the chain falling off the rear sprocket and help your scooter main-
tain optimum performance.
Properly adjusted, the chain should have 5-6mm (1/4”) of up-and-down travel
or slack.
