if you want OE pistons you need to have good straight bores within 81-81.4mm, but if you buy pistons stay sub 82mm. Wiseco do 81.5mm and 81.75mm i think. once you go over that there isnt much liner left and its a MUST you shim the expansion gap between the liners to avoid cracking due to flex. Basically what kills the 83mm bore engines, which people end up having to drop Dartons into when they crack (not cheap)
i shim anything i take the top off these days just because.
