I have a good but used 690 piston if you really want to push the limit!!  For an XTZ really, you'd probably need a new liner, and possibly open out the crankcase mouth.  Not for the faint-hearted.

Bit of info (not much) here:

and have a look at the blog site.  Thats the motor the 690 came off of.
