The chain always moves when you are fitting it on. the coloured link on crank sprocket probably jumped and you were not paying attention when it happened
No it was all timed up correctly with tensioner and guide rails in place - and then i rotated twice - about two weeks later i heard a screech on start up it so if it has jumped then it was after instal. The images i posted on this thread are of my old chain before i removed it - the crank sprocket is out on that only because of excessive mileage
