damage to the sprockets.
Service the chain more often if your
vehicle is used on dusty or muddy
roads.
WARNING
Before carrying out the fo llowing
operations, let the engine and the
exhaust silencer cool down until they
reach room temperature.
Failure to observe this warning can lead
to serious burns.
WARNING
Keep your fingers well clear of the chain
and sprocket, especially if you are
turning the rear wheel while working on
the vehicle. You can easily be seriously
injured if a finger is caught between the
chain and sprocket. Use work-gloves to
carrying out these operations.
CHECKING THE PLAY
To check the play:
Stop the engine.
Place the vehicle on the stand, see page 77
(PLACING THE VEHICLE ON THE
STAND).
Shift to neutral.
Check the chain play. It should be
0.98 in
(25 mm)
at mid-bottom span as shown
above.
Move the vehicle forward or backward, or
support the rear wheel in the air and turn
the wheel to several positions, to check the
chain slack at several locations. If the slack
is markedly different with the wheel in
different positions, the chain and sprockets
must be replaced.
WARNING
Never operate your vehicle with a
damaged chain. This could cause wheel
seizure which could lead to an upset and
result in serious injury or death. Lubricate
the chain frequently to minimize the
possibility of this kind of damage, see
pa g e 1 0 7 ( C L E A N I N G A N D
LUBRICATION).
If the play is the same at several locations, but
is more or less than
0.98 in (25 mm)
, adjust it,
see below (ADJUSTMENT).
