MAINTENANCE WORK ON CHASSIS AND ENGINE

Chain maintenance
For a long chain life, good maintenance is very important. Chains without
X-rings should be cleaned in fireproof solvent regularly and afterwards treated
with hot grease or chain spray (e.g. Motorex Chainlube 622).
X-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 X-ring chain spray (e.g. Motorex Chainlube
622).
NO LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISKS,
OTHERWISE THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS
WOULD BE STRONGLY REDUCED AND THE MOTORCYCLE COULD EASILY LOSE
CONTROL.
WHEN MOUNTING THE CHAIN MASTERLINK CLIP, THE CLOSED SIDE OF THE
MASTERLINK CLIP MUST POINT IN RUNNING DIRECTION.
Also check sprockets and chain guides for wear and replace if necessary.
Chain wear
To check the chain wear, observe the following indications:
Shift the gear into idling and pull the upper chain strand with approx. 10-15
Kilograms (33 lb) upwards (see figure). Now one can measure a space of 18
chain reels at the lower chain strand. The chain should be replaced at the
latest when a space of 272 mm (10.70 in) is measured. Chains do not always
wear off evenly, therefore repeat the measurement at different places on the
chain.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New chains
wear faster if used on old used sprockets.
SECURE THE SCREWS OF THE CHAIN WHEEL BY APPLYING LOCTITE AND FASTEN
THEM IN A CROSSWISE ORDER.
