Bore size (std) is 52.4 for the KPV, maybe just a way to use a worn-out cylinder that is too big for a KPV piston now? I suspect it won’t run very well, the port timing is altered a bit by those bottom spacers…not sure it is a big deal, probably not a race legal cylinder anyway, but I’m not an “expert”, don’t even play one on tv…
