had the cover off the flywheel just checking all was still tight,the nut was tight but i could feel some up/down side to side movement in the flywheel,not much just wondering if this is normal also it was the same with the balance shaft but i could see the movement in the balance shaft is this normal or do i need to whip the box out and start replacing bearings(the bearings i should have replaced at the start when the box was off the bike help please

I agree - it looks very much like you have some bearings to replace There really should not be any play in the things you have mentioned.

as i was building it up i knew i should have changed them but they seemed ok never mind will just have to whip the box out and replace them,shouldnt take to long
