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.
