How much slack should a motorcycle chain have?
Push up on the bottom of the chain and note the distance between the full-slack (lower) position and the no-slack (upper) position on the bottom . 1.2–1.6 inches (30–40 mm) is typical for streetbikes, while dirt bikes may need 1.4–2.0 inches (35–50 mm) of slack.
How do you check a motorcycle chain slack with a ruler?
