Checking chain tension
To check chain tension, turn off the engine and shift into neutral. Chain
tension is correct when the chain can just barely be pushed up to touch the
swingarm at the level of the screw
1
(see illustration). If necessary, correct
chain tension.

Chain maintenance
For long chain life, good maintenance is very important. X-ring chains
require only modest maintenance. The best way is to use lots of water, but
never use brushes or solvents. After letting the chain dry, you can use a
special X-ring chain spray (Shell Advance Bio Chain).
WARNING
N
O LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISK
,
EITHERWISE
THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS WOULD BE STRONGLY
REDUCED AND THE MOTORCYCLE COULD EASILY GET OUT OF CONTROL

Also check sprockets and chain guides for wear, and replace if necessary.
