Chain Tightening
The drive chain will
wear with use and requires periodic adjustment.
Chain
slack is measured by pushing down on chain between
the two sprockets. The amount of slack should
be 3/8”-1/2”. To tighten chain, loosen
the four bolts on the bottom of the engine and pull
the engine backwards. Note: mini-bikes with centrifugal
clutches, the engine will need to be pushed forward.

Chain Lubrication
For long life of chain, lubrication
is required before each ride. This can be accomplished
by using a non-oil based graphite spray. Do not use
oil or grease on the chain. Oil and grease attract
dirt and dust, which will shorten the life of the chain.
