coil pack help please

[born2die]

can someone please tell me how easy is it to change the coil pack on an activa and any pitfalls that I might encounter. I am not mechanically brilliant so would this best be left to the experts or is it something that I can do to build up a little confidence.
Thanks in advance

if its as easy as my ZX its just pull off HT's, unscrew, unclip king wire. also if like mine you will probably find that the stupid star bolt cross as they seem to be made out of cheese!
