Call me optimistic , but does anyone have a barrel that's not too far out from 82 mm and hopefully a piston to suit , for a 1937 BSA Empire Star . I already have one that's 60 thousandths over . Failing that any suggestions for sleeving an already sleeved cylinder . As you can imagine cracks have appeared in the bottom 1/2 inch . ( 82mm is 3.228 inches ) I am based in Melbourne Australia .
