some tips that you might find useful or choose to ignore:
- removing the end can and pillion foot rest hangers is not necessary but improves access, especially if you intend to torque up the torque arm forward nut when done
- wrapping the left side of the arm with newspaper when removing and re-fitting protects it from being scratched by the chain
- shock doesn't have to come out but loosening the top mounting bolt helps it swing out of the way
- cutting a piece of timber and jamming it between the floor and the undertray will prevent any pivoting accidents while there's no rear wheel in. you may not lean on the seat but visiting mates or children....
otherwise it's a simple case of unbolting everything. there's no clips or split pins or left handed threads or anything else out of the ordinary.
