Firstly there should have been no need to split the cases to change the pistons or rings.

If they are not closing then something must be in the way, most likely suspect is gearbox/selector forks etc, have you taken a torch and looked around the edges, also does everything look flush and like it will go back together if you look at the two crankcase Half's?

Also, don't try and force the cases together, if there is a gap then they are not correctly seated, all you will do by forcing them is damage something expensive...
