Warning
Danger of accidents Danger caused by incorrect chain tension.
–
If the chain is too taut, the components of the secondary power transmission (chain, engine sprocket, rear sprocket, bear-
ings in the transmission and in the rear wheel) will be under additional load. In addition to premature wear, this can cause
the chain or the countershaft of the transmission to break in extreme cases. If the chain is too loose, however, it may fall
off the engine sprocket or rear sprocket and block the rear wheel or damage the engine. Ensure that the chain tension is
correct and adjust it if necessary.
