Step By Step: How To Inspect, Lubricate, and Adjust a Motorcycle Chain

Using a tape measure (or visual estimation, if necessary), grasp the chain at a point halfway between the front and rear sprockets, and pull it up and down. The chain should be able to move roughly one inch up and one inch down. If your motorcycle is on a rear stand or centerstand, note that the swingarm will drop if the wheel is lifted from the ground, which will affect the rear geometry and the tension in the chain; compensate accordingly, if necessary.

Because motorcycle chains can stiffen in certain spots and stay pliable in others, it's important to roll the bike forward (or turn the rear wheel if it's on a stand) and check all sections of the chain. If it moves more than about an inch, the chain will need tightening, and if it's too tight, loosening will be in order; this is outlined in subsequent steps. If individual chain links are too tight, the chain might need replacement.
