CHECK AND ADJUST THE CHAIN TENSION
The chain can transfer the output-power from the
engine to the wheels, so that the motorcycle can move
normally. It is an important part of the motorcycle.
Therefore, the chain needs frequent inspection and
maintenance to ensure its normal use.
The chain tension can be adjusted according to
requirements, the steps are as follows:
1.
Stand the motorcycle with rear wheel suspended.
2.
Measure the distance between the rear fork and the
chain. The normal distance should be 30-40mm,
which is about the length of two fingers. It is not
necessary to strictly demand it, within the normal
distance is ok.
3.
Loosen the rear axle nut;
4.
Find the specific position with the greatest tension
on the chain when the distance is within the normal
range.
5.
By using the notches on the tensioner and the lugs
on the adjuster, through the nut on the tensioner,
adjust the fork properly.
6.
Tighten the tensioner nut.
7.
Tighten the rear axle nut.
8.
Check the point of maximum tension and re-adjust
the tension if necessary.
When checking the chain tension, you should also check the chain guide and sprocket through
visual inspection not limited to chain.
When the chain is over-used, or the stretch exceeds 2%, the chain should be replaced, and change
the relevant guide rail and sprocket at the same time. If only replace the chain without replacing
other accessories, the new chain will be easy worn out due to the worn accessories and shorten the
service life, meanwhile these accessories will quickly reach the limit of use and must be replaced.
Therefore, even from an economic point of view, it is worthwhile to replace the entire chain drive
system at the same time.
At any time, you should use the original parts from KAYO factory or the ones authorized by
KAYO.
The chain needs to be lubricated regularly, see the lubrication section for details.
NOTE
: The alternating wet and dry working environment will greatly shorten the service life of the
chain and its surrounding accessories. Therefore, please follow the correct lubrication method and
select a suitable lubricant for lubrication.
NOTE
: If the chain needs to be tightened frequently, or if you find any signs of wear on the front
