DT3 PISTON O.S. was created by Steve F

Need a little info for DT3 250 top end.
I need a new piston kit for my project
Bore is on 2 O,S,  70.50MM
I'm not finding anything larger than that for sale.
Is this bore at max size?

No, yamy goes to 1mm officialy but might be aftermarket up to 2mm over.
Trouble is knowing what fits what & likely later piston kits like DT250 up to "79 or whenever they ended would fit.
First google brings this up & as an example & i'd be surprised if it doesn't fit but others i hope will know!!?

Have a look at the Mitaka website. DT250MX piston, might fit, and there are drawings, which will confirm fit or not.
