TRANSMISSION CHAIN ADJUSTMENT
We suggest you to change your transmission chain in Skyteam's service station or dealer's station
when it has been worn.
To ensure the safety, you should make checks and adjustments to the transmission chain
before riding.
When performing the periodical check, the following states of drive chain should be checked.
(1)Loose pins (2)Damaged rolls (3)Dry and rusty chain links (4)Excessive damages (5)Twisted and bonded
links (6)Loosely adjusted chain
If the above troubles are found, the sprocket is most likely to be damaged. Therefore the following
check of the sprocket is necessary.
(1)Excessively worn sprocket teeth.
(2)Broken or damaged sprocket teeth.
(3)Loosened locking nuts of the sprocket.
After every 1,000km riding, adjust the transmission chain tension
according to the following method to ensure the sag is between 15-25mm.
Depending on your riding conditions, you may make frequent adjustment.
For every 1,000km riding at most, adjust the transmission chain tension. In fact you'd better
to adjust before every riding. Excessive chain slack could cause the chain to come off the
sprockets and result in an accident or serious engine damage. The transmission chain
adjustment should be conducted as per following methods:
