Err, if I remember correctly .40" is over 1mm oversize so no, I'd very much doubt standard pistons would last more than a couple of days before rattling themselves to death. Generally I use Wiseco pistons for my rebuild work. Not 100% they do them for this engine but it's likely as they do most applications & if it's not listed then you can usually give them the spec. you require & they have something suitable in stock.

No doubt someone with more experience of these motors has a different recommendation for you if you give it a while, but personally I've never had any issues with Wiseco in quality or pricing...
