Boring over a 250ex

I have a Honda 2003 TRX250ex. Piston blew apart. In its self distruction it tore up the cylinder wall pretty good, but not so bad I can't bore it clean. However, it is going to go about 050 over. Any idea's on what piston I can stick back in? I haven't seen any 250ex pistons more than 040, and I cannot confirm a possible piston pin change or lenght of a 300ex piston of the same year, or if it is even possible to use. Any help would be great. Thanks.

Wesco doesn't have a factory piston that goes large enough...236cc is as high as they have for a 250ex. Now that doesn't mean they don't have a piston that will fit, just not sure how to look for it.
