zx6r 2000 big ends

hi everyone.
As the title suggests I have done the big end on my 6 and am considering replacing them myself.
Anyone done this and how hard is it.
AAny advise appreciated, Haters stay away
If anyone has any constructive advise I am keen to listen. I know its not as easy as changing the oil ha ha, But I am a uni student and dont have the mulah to get the local to do it. Does anyone have the manual or know where I can get a copy
