I was thinking of this size also, what is the piston size 88mm? Does someone make a cast piston for this? I assume with the larger bore you could do a little more porting. Mike
Hi Owen, the couple 925s I have seen have all had the engine in a basket from piston failures. I have had nothing but bad luck with Wiseco pistons. So unless you can find another brand I'd go with the 975 instead.
