Hello I've got a 1994 Polaris xlt sks 600 that has a bad engine and I've discovered it is much Easyer to find one through eBay that I can just bolt in and go. So my question is what bigger engines will fit with minor mods , I just seen a nice 97 700 big bore that looks pretty sweet

But I don't know the limitations or bounderies I half to choose from the bigger the bader I always say.any suggestions? Thanks
