93 kx250 bore, how big can it go?

i have a sleeved 93 kx250 cylinder. whats the biggest piston i can get for this?
i think its bored out to the last piston wiesco lists, i'll have to measure it again. theres plenty of meat left, is there any companies that sell an oversize piston? other than wiesco

you might try a '87-'89 piston... they make them up to 69.5mm

its bored 68.5 the stroke is differnet on that year may not work right??

if i can just get a 69mm piston for this year i'll be all set! lol

2mm difference in stroke... I have a piston that I could take some measurements or pictures of... Maybe the 1mm is made up in the cylinder height?
