Notice: A drive chain that is too tight will overload the engine and other vital parts, and one that is too loose can skip and damage the swingarm or cause an accident. Therefore, keep the drive chain slack within the specified limits.
1. Stand the vehicle on a level surface.
Warning: Securely support the vehicle so that there is no danger of it falling over.
Place the vehicle on a suitable stand so that the rear wheel is elevated.
2. Move the rear wheel several times and find the tightest position of drive chain.
3. Check:
- Drive chain slack "a"
