CHECK THE STRUCTURE OF THE REAR SPROCKET, ENGINE SPROCKET AND GUIDE
CHAIN
Check the condition of the swinging arm rubber and the
chain guide as per the guide photos.
Under normal circumstances, these two parts play a
role in guiding the movement of the chain. If they are
over worn this will affect the transmission function and
thereby be harmful to normal movement of the chain
and other components of the motorcycle.
Therefore, you must change the over-worn chain guide
and chain protector in order to ensure that the
motorcycle works normally.
CHECK THE FRAME
Checking Steps are as follows:
1. Check whether the paint on the surface of the frame is damaged or not.
2. Check whether the fixed points of the frame are deformed or not, especially the installation
points of the engine, swinging arm and rear shock absorber.
3. Check whether there are cracks on the surface of the frame, especially on the welded areas.
CHECK THE SWINGING ARM
Checking Steps are as follows
1 Check whether there are cracks on the surface of
the swinging arm
2 Check whether there is any deformation at the
mounting point where the swinging arm joins the
frame.
3 Check whether the paint of the swinging arm is
damaged or not.
CHECK THE THROTTLE CABLE
Checking Steps are as follows:
1 Turn the throttle and release, to observe whether the
throttle is smooth and returns properly.
2 If there is excess play in the cable as you turn the
throttle , this can be adjusted to the correct setting on
the top of the carburettor .
