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 (Motorex Chainlube Racing).

Chain wear
In order to check the chain wear, regard the following instructions:
Shift the gear into idling and pull the upper chain strand with approx. 10-15
kilogramm (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 (10.88 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.
