A1Difficulty 3/5

During maintenance of a motorcycle with a chain drive requiring adjustment and lubrication, how should chain slack be handled?

Correct answer

Check it, adjust if necessary and lubricate as specified by the manufacturer.

Check slack and adjust when necessary to the manufacturer’s specified range; clean and lubricate with prescribed products and frequency. Some slack is normal and necessary: do not eliminate it or leave excessive slack. The value, checking position and procedure depend on the model. Not every inspection requires tightening; worn chain or sprockets may need replacement.
