its normal use.
The chain tension can be adjusted according to requirements, as shown below:
1.The motorcycle is fixed so that the rear wheel is completely suspended;
2.Measure the distance between the back of the swing arm and the chain, the normal distance should be 30 ~
40mm, about the width of two fingers. The distance is close to the normal distance, do not have to be very
demanding;
3.Loosen the rear axle nut;
4.Find the position of maximum tension in the chain under the condition of satisfying the normal spacing;
5.Through the nut on the tensioner, using the notch on the tensioner and the lugs on the adjuster, make the two
ends of the awing arm aligned;
6.Screw the tensioner nut;
7.Tighten the rear axle nut;
8.Check the maximum tension point and readjust the tension if necessary.
When checking the chain tension, in addition to the chain, the guide rail and sprocket of the chain should also be
visually inspected.
When the chain is used excessively or the stretching amount exceeds 2%, the chain should be replaced, and the
corresponding guide rail and sprocket should also be replaced. If the chain is only replaced without other parts, the
service life of the new chain will be shortened due to the wear and tear of other parts caused by the old chain, and
these parts will soon reach the limit of use, so that they have to be replaced. Therefore, even from an economic
point of view, it is worthwhile to replace the whole chain drive system at the same time. The replacement parts
should use the original production or authorized products of KAYO.
The chain needs to be lubricated regularly, see General Lubrication section for details.
Note:
alternately wet and dry working conditions will greatly shorten the service life of the chain and its
surrounding parts. Therefore, please choose the appropriate lubricant according to the correct lubrication method.
Note:
if the chain needs to be frequently tension, or you find any signs of wear on the front sprocket, rear sprocket
and chain, please contact KAYO dealer for a comprehensive inspection to avoid safety problems.
Inspect rear sprocket, engine sprocket and chain guide structure
Chain slider
Chain roller
Chain guard
Check the wear of the chain slider and chain guard on the
swing arm. Under normal circumstances, these two can play a
role in guiding the chain movement, if the wear is too severe, it
is not conducive to the normal movement of the chain, affecting
its transmission function. So severely worn chain slider and
chain guard should be replaced in time to ensure the normal
work of the motorcycle.
Inspection of the frame
The frame inspection work is carried out from the following aspects:
1.Check whether the paint layer on the frame surface is damaged;
2.Check whether the fixed points of the frame are deformed, especially the installation points of the engine, swing
arm and rear shock;
3.Check whether there are cracks on the surface of the frame, especially in the welding parts of the frame.
