I've been told that the polaris Xpedition 425 have basically the same engine as polaris 500. The only difference is bore and stroke. does anyone know if it is possible to put a 500 sleeve and piston in a 425? I think the cc would end up being around 465cc. Would it be worth the trouble? I really want more torque to spin triclaws in heavy thick mud and to be able to spin 27 inch tires in second gear.

Any help is appreciated.
