does one remove the balance chain and sprockets without turning the shafts? How is it re-assembled?

mutangi.yes remove sprockets without turning
shafts,you dont say whether or not you have balance shafts,I would suggest that you purchase,beg borrow or steal a Haynes manual,as the job is far too complex to type out here.
Good luck
