Check chain tension
To check the chain tension, park the motorcycle.
Press chain upward at the end of the chain sliding component. The distance
between chain and swing arm should be approx. 15 mm (0.6 in). In the
course of this procedure, the upper chain portion A must be taut (see
illustration).
If necessary, correct chain tension.

NOTE:
The large adjusting range of the chain adjusters (32mm) allows you to use
different secondary ratios in combination with the same chain length. The
chain adjusters 4 can be rotated around 180°.
Chain maintenance
For long chain life, good maintenance is very important. Chains without O-
rings should be cleaned in fireproof solvent regularly and afterwards treated
with hot grease or chain spray (i.e. Shell Advance Bio Chain).
O-ring chains on the other hand are very simple to clean. The best way is to
use lots of water, but never use brushes or cleaning liquids. After letting the
chain dry, you can use a special O-ring chain spray (i.e. Shell Advance Bio
Chain).
