I guess I should have asked it different, like engine for engine, the cost difference between the two.
Really though I already know, not directly with yours, but just in general from what I know the 4 stroke will cost more. Those 4 strokes are doing just what the MFGs designed them to do, rob the bike & ATV racers of their money because they are just easier to ride, but cost more to build & keep running.
That Can Am, if you could throw that head in the trash & bolt a 450 Honda head on it, you could get some real performance out of it. Theres some 4 poke builders wont even touch that head, its just to much trouble to deal with. Now if you could take one & weld closed the intake & then machine it back out, maybe just maybe it might could be fixed.
Oh, now Can Am does have a good SXS. If you had a Can Am SXS & a Polaris SXS, that Polaris SXS would wear the Can Am out, because you would be running the Can Am all the time from that Polaris being broke down.
