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 indications:
Shift the gear into idling and pull the upper chain strand with approx.
10-15 kilogram (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.
