Carefully read p. 55 (MAINTENANCE).
The vehicle is equipped with an endless
chain, in which a ring link joint is not used.
CAUTION
An excessive slackening of the chain
may cause noise or make the chain rat-
tle, with consequent wear of the shoe
and of the chain guide plate.
Periodically check the slack and adjust
it if necessary, see beside (ADJUST-
MENT).
To change the chain, contact an
Official Dealer, who will ensure you
prompt and accurate servicing.
Incorrect maintenance may cause the
untimely wear of the chain and/or dam-
ages to the pinion and/or the crown.

use and maintenance RSV mille - RSV mille R
CAUTION
Carry out the maintenance operations
more frequently if you use the vehicle in
difficult conditions or on dusty and/or
muddy roads.
CHECKING THE SLACK
To check the slack, proceed as follows:
N
Stop the engine.
N
Position the vehicle on the side stand on
firm and level ground.
N
Position the shifting lever in neutral.
N
Make sure that the vertical oscillation, in
an intermediate point between pinion
and crown in the lower part of the chain,
is about 25 mm.
N
Move the vehicle forwards, or turn the
wheel, in order to be able to check the
vertical oscillation of the chain even
when the wheel turns; the slack must be
constant in all the rotation phases of the
wheel.
CAUTION
If in some positions the slack is higher
than in others, this means that there are
crushed or seized links; in this case,
contact an
Official Dealer. To
prevent the risk of seizures, lubricate the
chain frequently, see p. 69 (CLEANING
AND LUBRICATION).
If the slack is uniform, but higher or lower
than 25 mm, adjust it, see beside (AD-
JUSTMENT).
ADJUSTMENT
NOTE
To adjust the chain it is necessary
to use the appropriate rear support stand
.
If after the check it is necessary to adjust
the chain tension, proceed as follows:
N
Position the vehicle on the appropriate
rear support stand, see p. 62 (POSI-
TIONING THE VEHICLE ON THE REAR
SUPPORT STAND
).
N
Loosen the nut (1) completely.
NOTE
For the wheel centering fixed ref-
erence marks (2-3) are provided, which
can be seen inside the chain tightener
seats on the rear fork arms, before the
wheel pin.
