Warning
Danger of accidents Incorrect chain tension damages components and results in accidents.

ings 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.
