So , I got a newer 700 twin, the piston to wall clearance right from the factory is huge, I`m thinking around .012 to .014 if I put in  .010 oversize pistons from say wiesco or oem and in the end wound up with say .003 to .0050 clearence,  is there anything I should know about as far as expansion rates? Was there a idiocinctracy  about the 700 doo twin  motor,  where it somhow needed big clearences?? Pistons can be built to expand differently, is there a manufactuer that adresess  this?
