    GP1200R or 1300R stroker question

    What is the biggest stroke that can be run in the 1200r or 1300r cases? Also, if using aftermarket cylinders, what is the biggest bore that can be run with those cases? I am not a watercraft guy, but a snowmobile race guy, and want to build another stroker race motor, using Price Performance cylinders......my 263hp 1136cc motor isn't cutting it anymore
