Will the barrel liner bore to 86mm and leave enough wall in , found a B33 long rod plus 40 piston, all the very best

With Ian's help, I calculated that there was enough wall thickness to accept my standard B33 piston (85mm) Another 1/2mm off the wall thickness might be pushing it a bit?? Ron

Cheers for that Ron , I will give the plus 40 piston a miss and try to find a standard 85mm
