 Some 750 pistons can be used, but require some machining around the crown, I'm not sure on which models fit though. I was lucky enough to pick up some NOS 61mm wiseco's for mine, specifically for the 650, these pistons are NLA though.  HiPo parts for the 650 are hard to come by though. 
Here's a link to fitting larger pistons to the 650/550
