11 SERVICE WORK ON THE CHASSIS 51
11.39 Adjusting the chain tension
Warning
Danger of accidents Incorrect chain tension damages components and results in accidents.
If the chain is tensioned too much, the chain, engine sprocket, rear sprocket, transmission and rear wheel bearings wear
more quickly. Some components may break if overloaded.
If the chain is too loose, the chain may fall off the engine sprocket or the rear sprocket. As a result, the rear wheel locks or
the engine will be damaged.
– Check the chain tension regularly.
– Set the chain tension in accordance with the specification.
