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 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 (10,70 in) is measured. Chains do not
always wear off evenly, therefore repeat the measurement at different pla-
ces 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.
