It is important to check sprockets for wear periodically. If wear occurs on the side of the teeth, it means there is misalignment, a condition which will result in greatly reduced chain life. Check sprocket alignment visually by sighting across them from the rear of the motorcycle or by placing a ruler against them to see if they are in the same plane. Realign or replace as required. When new sprockets are installed, they should be carefully aligned on the shafts with a straight edge.
Misalignment increases drive noise level and also increases chain and sprocket wear.
Chains operating on misaligned sprockets have a tendency to develop tight joints because sprocket teeth force the inside plates outward on the bushings,thus binding the joint.
