5. Measure/Cut The New ChainMeasuring Chain

If you’re using the same size sprockets, lay the old chain down on a clean surface beside the new one to mark the length. Now, pop the pin out of the new chain to cut it to the correct number of links. For different sprocket sizes, you’ll measure the chain to length once the sprockets are mounted. Wrap the new chain around both sprockets. If the chain has not been cut to length, turn the chain adjusters in equal amounts until the middle of the adjustment range is indicated on the swingarm. Snug up the axle nut to keep the axle from moving. Pull the chain taut and fold the chain over where it meets the other end. You goal is to mark the rivet that needs to be removed so that you can slip the master link into position. Remove the rivet as described earlier.
